Time zones worksheet comparing London and Beijing times.

Let's solve the problem step by step.

Problem:

In the winter, the time in Beijing, China is 1 hour later than that in London. We are given a table with times in either London or Beijing and need to complete the missing times based on this 1-hour difference.

---

Key Rule:

- Beijing = London + 1 hour
- So, if you know the time in London, add 1 hour to get Beijing time.
- If you know the time in Beijing, subtract 1 hour to get London time.

We'll go through each row and fill in the missing time accordingly.

---

Given Table:

| Time in London | Time in Beijing |
|----------------|-----------------|
| 4 o'clock | |
| 1:00 | |
| 7 o'clock | 9 o'clock |
| | 10:00 |
| | 4:00 |
| Half past 8 | Quarter past 12 |
| 8:30 | |
| 2:45 | |
| | 11:49 |
| Quarter to 3 | 1:08 |
| 3:50 | |

Now let’s fill in the blanks one by one.

---

Row 1:

- London: 4 o'clock → Beijing: 4 + 1 = 5 o'clock

✔ Beijing: 5 o'clock

---

Row 2:

- London: 1:00 → Beijing: 1:00 + 1 = 2:00

✔ Beijing: 2:00

---

Row 3:

- London: 7 o'clock
- Beijing: 9 o'clock

Check: 7 + 1 = 8 → but Beijing says 9 → That’s 2 hours ahead, not 1. ✘

Wait — this contradicts the rule unless there's an error.

But the problem says in winter, Beijing is 1 hour ahead of London.

So if Beijing is 9 o'clock, then London should be 8 o'clock.

But it says London: 7 o'clock → that would make Beijing 8 o'clock, not 9.

So something’s wrong here.

Wait — maybe I misread.

Let’s check again.

Row 3:
- London: 7 o'clock
- Beijing: 9 o'clock

That’s 2 hours difference, but we're told Beijing is only 1 hour ahead.

So either:
- The data is incorrect, or
- There's a typo, or
- We need to re-evaluate.

But wait — perhaps this row is meant to be filled in? No, both values are given.

Wait — actually, both are given, so we can check consistency.

But 7:00 London → 9:00 Beijing implies 2 hours ahead, which contradicts the stated 1-hour difference.

So this suggests a mistake?

But let’s keep going and see.

Wait — maybe it's a typo, or maybe I’m misunderstanding.

Alternatively, perhaps this row has a typo, or maybe the rule is different?

But the problem clearly says: "In the winter the time in Beijing, China is 1 hour later than that in London."

So Beijing = London + 1 hour

So if London is 7:00, Beijing must be 8:00.

But it says Beijing is 9:00 → that’s inconsistent.

So perhaps this is a mistake in the worksheet, or perhaps we’re supposed to ignore it?

Wait — no, let’s look at other rows.

Row 4:

- Beijing: 10:00 → London: 10:00 - 1 = 9:00

✔ London: 9:00

---

Row 5:

- Beijing: 4:00 → London: 4:00 - 1 = 3:00

✔ London: 3:00

---

Row 6:

- London: Half past 8 → 8:30
- Beijing: Quarter past 12 → 12:15

Now check: 8:30 + 1 = 9:30 → but Beijing is 12:15 → that’s 3.5 hours ahead → ✘ Not consistent.

This is a big problem.

So either:
- The problem has errors,
- Or I'm misunderstanding the task.

Wait — maybe the worksheet has typos, or perhaps I need to recheck.

Wait — could it be that "Quarter past 12" means 12:15, and Half past 8 is 8:30.

But 8:30 + 1 = 9:30, not 12:15 → huge discrepancy.

So this row also doesn't match.

Similarly, next row:

Row 7:

- London: 8:30 → Beijing: 8:30 + 1 = 9:30

✔ Beijing: 9:30

But in previous row (row 6), same London time (8:30) had Beijing as 12:15 → contradiction.

So likely, row 6 is incorrectly filled.

But in row 6, both times are given.

So either:
- The worksheet has errors, or
- I am misreading the labels.

Wait — let’s look carefully at row 6:

> Half past 8 → Quarter past 12

It says:
- Time in London: Half past 8 → 8:30
- Time in Beijing: Quarter past 12 → 12:15

But 8:30 + 1 = 9:30 ≠ 12:15 → impossible.

So this must be a mistake in the worksheet.

Alternatively, maybe "Quarter past 12" is a typo, and it should be quarter past 9?

Or maybe "Half past 8" is in Beijing?

But the column headers say:

| Time in London | Time in Beijing |

So left column is London, right is Beijing.

So unless the label is swapped, it’s inconsistent.

Perhaps the only way this makes sense is if we assume the given times are correct, and we deduce the pattern.

But that contradicts the stated rule.

Wait — let’s look at row 10:

Row 10:

- London: Quarter to 3 → 2:45
- Beijing: 1:08

2:45 + 1 = 3:45 → but Beijing is 1:08 → not matching.

So again, contradiction.

And row 11:
- London: 3:50 → Beijing: ?

3:50 + 1 = 4:50 → so Beijing should be 4:50.

But earlier rows show inconsistencies.

Wait — perhaps I made a mistake in reading the table.

Let me reconstruct the table carefully from the image description.

Looking back:

```
Time in London | Time in Beijing
----------------------|------------------
4 o'clock |
1:00 |
7 o'clock | 9 o'clock
| 10:00
| 4:00
Half past 8 | Quarter past 12
8:30 |
2:45 |
| 11:49
Quarter to 3 | 1:08
3:50 |
```

So the blank cells are:

- Row 1: Beijing
- Row 2: Beijing
- Row 3: London (but given 7:00, Beijing 9:00) → inconsistency
- Row 4: London
- Row 5: London
- Row 6: Both given → conflict
- Row 7: Beijing
- Row 8: Beijing
- Row 9: London
- Row 10: London
- Row 11: Beijing

But many of the given pairs don’t follow the 1-hour rule.

For example:

- Row 3: London 7:00, Beijing 9:00 → 2 hours → invalid
- Row 6: London 8:30, Beijing 12:15 → 3.5 hours → invalid
- Row 10: London 2:45, Beijing 1:08 → 1:08 is earlier → impossible

Unless Beijing is behind, but the problem says Beijing is 1 hour ahead.

Also, row 10: Beijing 1:08, London quarter to 3 = 2:45 → Beijing is earlier → impossible.

So clearly, some entries are wrong, or the rule is different.

Wait — perhaps the time difference is not always 1 hour, or maybe it's daylight saving?

But the problem says: "In the winter, the time in Beijing is 1 hour later than London."

So in winter, Beijing is 1 hour ahead of London.

Standard time difference between London (GMT) and Beijing (CST) is +8 hours, but due to daylight saving, sometimes it's 7 or 8.

Wait — hold on! This might be the key.

Real-world knowledge:

- London uses GMT in winter (no DST)
- Beijing uses China Standard Time (CST) = UTC+8
- So Beijing is 8 hours ahead of London in winter.

But the problem says: "1 hour later than that in London"

"Later" means ahead in time.

So if Beijing is 1 hour later than London, that means Beijing is 1 hour ahead.

But in reality, it's 8 hours ahead, not 1.

So either:
- The problem is fictional/educational, using a simplified 1-hour difference for teaching purposes, or
- It's a typo.

But since the problem states it, we must accept Beijing is 1 hour ahead of London for this exercise.

So we proceed with Beijing = London + 1 hour

Now, let’s go row by row and fill in the blanks, assuming the given times are correct if possible, but note that some rows have conflicts.

But let’s try to fix them.

Wait — perhaps the given times are correct, and we are to use the rule to fill blanks.

But in row 3: London 7:00, Beijing 9:00 → that’s 2 hours → not 1 → so cannot be.

Unless the rule is wrong.

But the problem says "is 1 hour later".

So maybe the worksheet has typos, or perhaps I'm misreading the table.

Let me assume that all given times are correct, and see what the actual time difference is.

But that would contradict the problem statement.

Alternative idea: Perhaps the "1 hour later" is a mistake, and it should be 8 hours later?

But that would make the worksheet even more inconsistent.

Let’s try to find consistent rows.

Look at row 10:
- London: Quarter to 3 = 2:45
- Beijing: 1:08

If Beijing is 1 hour ahead, then when London is 2:45, Beijing should be 3:45.

But it’s 1:08 → not possible.

Unless it's next day, but 1:08 is earlier.

No.

Another possibility: Maybe "Quarter to 3" is in Beijing, and "1:08" is in London?

But the columns are labeled:

| Time in London | Time in Beijing |

So first column is London, second is Beijing.

So Quarter to 3 is London time → 2:45

1:08 is Beijing time → 1:08

Then Beijing is 1:08, London is 2:45 → Beijing is behind by 1h37m → impossible.

So this is invalid.

Similarly, row 6: London 8:30, Beijing 12:15 → Beijing is 3.5 hours ahead.

Not 1.

So only possible conclusion: The worksheet has errors.

But perhaps it's designed for students to learn how to apply the rule, and some rows are for practice.

Maybe the given times are correct, and we are to fill in the blanks, ignoring the inconsistencies.

But that doesn't make sense.

Wait — let’s look at row 4: Beijing 10:00 → London should be 9:00

Row 5: Beijing 4:00 → London 3:00

Row 7: London 8:30 → Beijing 9:30

Row 8: London 2:45 → Beijing 3:45

Row 11: London 3:50 → Beijing 4:50

Row 1: London 4:00 → Beijing 5:00

Row 2: London 1:00 → Beijing 2:00

Row 9: Beijing 11:49 → London 10:49

Row 10: Beijing 1:08 → London 12:08

Row 6: London 8:30 → Beijing 9:30 (not 12:15)

Row 3: London 7:00 → Beijing 8:00 (not 9:00)

So likely, the given values in row 3, 6, 10 are typos.

Perhaps:

- Row 3: Beijing should be 8:00, not 9:00
- Row 6: Beijing should be 9:30, not 12:15
- Row 10: Beijing 1:08 is wrong; should be 3:45

But we can't change the worksheet.

Alternatively, perhaps the rule is not always applied, or it's a trick.

But let's assume that the only reliable information is the rule, and the given times are to be used where they fit.

But we need to complete the table.

Perhaps the blank cells are to be filled using the rule, and the given times are correct when they are given.

But if a given pair doesn't satisfy the rule, then it's a problem.

Let’s list only the rows where one value is given and the other is blank.

Rows with one blank:

1. London: 4:00 → Beijing: ? → 4:00 + 1 = 5:00
2. London: 1:00 → Beijing: ? → 1:00 + 1 = 2:00
3. London: 7:00 → Beijing: 9:00 → but 7+1=8≠9 → invalid
4. Beijing: 10:00 → London: ? → 10:00 - 1 = 9:00
5. Beijing: 4:00 → London: ? → 4:00 - 1 = 3:00
6. London: 8:30 → Beijing: ? → 8:30 + 1 = 9:30
7. London: 2:45 → Beijing: ? → 2:45 + 1 = 3:45
8. Beijing: 11:49 → London: ? → 11:49 - 1 = 10:49
9. London: Quarter to 3 = 2:45 → Beijing: 1:08 → but 2:45 + 1 = 3:45 ≠ 1:08 → invalid
10. London: 3:50 → Beijing: ? → 3:50 + 1 = 4:50

Now, row 3 and row 9 have both values given, but they don't satisfy the rule.

So perhaps those are intentional mistakes for discussion, or perhaps the rule is different.

But the problem says "Complete the following", so we should fill in the blanks using the rule.

So let's fill in the blanks ignoring the conflicting given values.

So final completed table:

| Time in London | Time in Beijing |
|----------------|-----------------|
| 4 o'clock | 5 o'clock |
| 1:00 | 2:00 |
| 7 o'clock | 8 o'clock | (not 9:00, but we follow rule)
| 9:00 | 10:00 |
| 3:00 | 4:00 |
| 8:30 | 9:30 |
| 2:45 | 3:45 |
| 10:49 | 11:49 |
| 2:45 | 3:45 | (same as above)
| 3:50 | 4:50 |

Wait — row 9 has London: Quarter to 3 = 2:45, Beijing: 1:08

But we calculated Beijing should be 3:45.

So if we are to follow the rule, we must ignore the given Beijing time and put 3:45.

But the cell already has 1:08.

So likely, it's a typo, and we should write the correct time.

Perhaps the worksheet expects us to apply the rule regardless.

So let’s write the answers for the blank cells.

Final Answers:

1. 4 o'clock in London → Beijing: 5 o'clock
2. 1:00 in London → Beijing: 2:00
3. 7 o'clock in London → Beijing: 8 o'clock (not 9:00)
4. Beijing 10:00 → London: 9:00
5. Beijing 4:00 → London: 3:00
6. Half past 8 (8:30) in London → Beijing: 9:30
7. 8:30 in London → Beijing: 9:30
8. 2:45 in London → Beijing: 3:45
9. Beijing 11:49 → London: 10:49
10. Quarter to 3 (2:45) in London → Beijing: 3:45
11. 3:50 in London → Beijing: 4:50

Note: Some given values (like Beijing 9:00 for London 7:00, or Beijing 1:08 for London 2:45) are incorrect and should be ignored or corrected.

---

Conclusion:

The correct completed table (using the rule: Beijing = London + 1 hour) is:

| Time in London | Time in Beijing |
|----------------|-----------------|
| 4 o'clock | 5 o'clock |
| 1:00 | 2:00 |
| 7 o'clock | 8 o'clock |
| 9:00 | 10:00 |
| 3:00 | 4:00 |
| 8:30 | 9:30 |
| 2:45 | 3:45 |
| 10:49 | 11:49 |
| 2:45 | 3:45 |
| 3:50 | 4:50 |

(Note: The original worksheet has errors in rows 3, 6, and 10.)

---

Final Answer:

Fill in the blanks as follows:

- 5 o'clock
- 2:00
- 8 o'clock
- 9:00
- 3:00
- 9:30
- 3:45
- 10:49
- 3:45
- 4:50

These are the correct times based on the rule that Beijing is 1 hour ahead of London in winter.
