Time Zones (1) Worksheet for 5th - 6th Grade | Lesson Planet - Free Printable

Problem Description:

The task involves converting times between London and Beijing, given that Beijing is 8 hours ahead of London. The table provided requires filling in the corresponding times for each entry.

Solution Approach:

1. Understand the Time Difference:
- Beijing is 8 hours ahead of London.
- This means if it is a certain time in London, you add 8 hours to find the time in Beijing.
- Conversely, if it is a certain time in Beijing, you subtract 8 hours to find the time in London.

2. Fill in the Table:
- For each row, use the time difference rule to calculate the corresponding time in the other city.
- Ensure that the calculations wrap around the 12-hour clock (e.g., 10:00 PM + 8 hours = 6:00 AM the next day).

3. Step-by-Step Calculations:

#### Row 1: 4 o'clock in London
- Add 8 hours to 4:00 AM/PM.
- 4:00 AM + 8 hours = 12:00 PM (Noon).
- 4:00 PM + 8 hours = 12:00 AM (Midnight the next day).
- Since "4 o'clock" typically refers to AM in such contexts, we assume 4:00 AM.
- Time in Beijing: 12:00 PM (Noon).

#### Row 2: 1:00 in Beijing
- Subtract 8 hours from 1:00 AM/PM.
- 1:00 AM - 8 hours = 5:00 PM (previous day).
- 1:00 PM - 8 hours = 5:00 AM.
- Since "1:00" typically refers to PM in such contexts, we assume 1:00 PM.
- Time in London: 5:00 AM.

#### Row 3: 7 o'clock in London
- Add 8 hours to 7:00 AM/PM.
- 7:00 AM + 8 hours = 3:00 PM.
- 7:00 PM + 8 hours = 3:00 AM (next day).
- Since "7 o'clock" typically refers to AM in such contexts, we assume 7:00 AM.
- Time in Beijing: 3:00 PM.

#### Row 4: 9 o'clock in Beijing
- Subtract 8 hours from 9:00 AM/PM.
- 9:00 AM - 8 hours = 1:00 AM.
- 9:00 PM - 8 hours = 1:00 PM.
- Since "9 o'clock" typically refers to PM in such contexts, we assume 9:00 PM.
- Time in London: 1:00 PM.

#### Row 5: 10:00 in Beijing
- Subtract 8 hours from 10:00 AM/PM.
- 10:00 AM - 8 hours = 2:00 AM.
- 10:00 PM - 8 hours = 2:00 PM.
- Since "10:00" typically refers to PM in such contexts, we assume 10:00 PM.
- Time in London: 2:00 PM.

#### Row 6: 6:00 in London
- Add 8 hours to 6:00 AM/PM.
- 6:00 AM + 8 hours = 2:00 PM.
- 6:00 PM + 8 hours = 2:00 AM (next day).
- Since "6:00" typically refers to PM in such contexts, we assume 6:00 PM.
- Time in Beijing: 2:00 AM (next day).

#### Row 7: Half past 6 in London
- Half past 6 is 6:30.
- Add 8 hours to 6:30 AM/PM.
- 6:30 AM + 8 hours = 2:30 PM.
- 6:30 PM + 8 hours = 2:30 AM (next day).
- Since "half past 6" typically refers to PM in such contexts, we assume 6:30 PM.
- Time in Beijing: 2:30 AM (next day).

#### Row 8: Quarter past 12 in Beijing
- Quarter past 12 is 12:15.
- Subtract 8 hours from 12:15 AM/PM.
- 12:15 AM - 8 hours = 4:15 PM (previous day).
- 12:15 PM - 8 hours = 4:15 AM.
- Since "quarter past 12" typically refers to PM in such contexts, we assume 12:15 PM.
- Time in London: 4:15 AM.

#### Row 9: 8:30 in London
- Add 8 hours to 8:30 AM/PM.
- 8:30 AM + 8 hours = 4:30 PM.
- 8:30 PM + 8 hours = 4:30 AM (next day).
- Since "8:30" typically refers to PM in such contexts, we assume 8:30 PM.
- Time in Beijing: 4:30 AM (next day).

#### Row 10: 2:45 in London
- Add 8 hours to 2:45 AM/PM.
- 2:45 AM + 8 hours = 10:45 AM.
- 2:45 PM + 8 hours = 10:45 PM.
- Since "2:45" typically refers to PM in such contexts, we assume 2:45 PM.
- Time in Beijing: 10:45 PM.

#### Row 11: 11:49 in Beijing
- Subtract 8 hours from 11:49 AM/PM.
- 11:49 AM - 8 hours = 3:49 AM.
- 11:49 PM - 8 hours = 3:49 PM.
- Since "11:49" typically refers to PM in such contexts, we assume 11:49 PM.
- Time in London: 3:49 PM.

#### Row 12: Quarter to 5 in Beijing
- Quarter to 5 is 4:45.
- Subtract 8 hours from 4:45 AM/PM.
- 4:45 AM - 8 hours = 8:45 PM (previous day).
- 4:45 PM - 8 hours = 8:45 AM.
- Since "quarter to 5" typically refers to PM in such contexts, we assume 4:45 PM.
- Time in London: 8:45 AM.

#### Row 13: 1:08 in Beijing
- Subtract 8 hours from 1:08 AM/PM.
- 1:08 AM - 8 hours = 5:08 PM (previous day).
- 1:08 PM - 8 hours = 5:08 AM.
- Since "1:08" typically refers to PM in such contexts, we assume 1:08 PM.
- Time in London: 5:08 AM.

#### Row 14: 5:50 in London
- Add 8 hours to 5:50 AM/PM.
- 5:50 AM + 8 hours = 1:50 PM.
- 5:50 PM + 8 hours = 1:50 AM (next day).
- Since "5:50" typically refers to PM in such contexts, we assume 5:50 PM.
- Time in Beijing: 1:50 AM (next day).
