table listing cities around the world with their local times relative to GMT (e.g., London is 0:00, New York is -5:00, Tokyo is +9:00).
- The top title: "
GMT Time Around the World"
The right side shows:
- A
worksheet titled "
Time Zones" with several questions and blank tables for students to fill in.
- Questions likely ask students to:

🧠 Common Types of Problems & How to Solve Them
Let’s assume the task involves solving
time conversion problems using the GMT chart.
####
✔ Example Problem:
> "If it is 3:00 PM in London (GMT), what time is it in Tokyo?"
#### 🔎 Step-by-Step Solution:
1.
Find Tokyo’s GMT offset from the table:
- Tokyo is
+9 hours ahead of GMT.
2.
Add the offset to London’s time:
- 3:00 PM + 9 hours = 12:00 AM (midnight) the next day.
3.
Answer: It is
12:00 AM (midnight) in Tokyo.

####
✔ Another Example:
> "If it is 8:00 AM in New York (-5), what time is it in Sydney (+10)?"
1.
New York is -5, so when it's 8:00 AM there, GMT is:
- 8:00 AM + 5 hours =
1:00 PM GMT
2.
Sydney is +10, so add 10 hours to GMT:
- 1:00 PM + 10 hours =
11:00 PM in Sydney.
3.
Answer: It is
11:00 PM in Sydney.

📌 Key Tips for Solving Time Zone Problems
-
Use GMT as a bridge: Convert both times to GMT first, then convert to the target time zone.
-
Positive offsets mean the location is ahead of GMT (east).
-
Negative offsets mean the location is behind GMT (west).
-
Cross-day changes: If adding/subtracting hours crosses midnight, adjust the date accordingly.

🛠️ Worksheet Practice (Based on Layout)
Looking at the blank tables on the right:
- Students may be asked to:
- Fill in the time in different cities when one is given.
- Draw clocks showing the time in each city.
- Write the time difference between two locations.
For example:
| City | Time |
|-------------|------|
| London | 12:00 PM |
| New York | ? |
| Tokyo | ? |
→ Use the offsets:
- New York: 12:00 PM – 5 =
7:00 AM
- Tokyo: 12:00 PM + 9 =
9:00 PM

✔ Final Answer Format (Example)
>
Problem: If it is 6:00 PM in Paris (+1), what time is it in Los Angeles (-8)?
>
Solution:
> - Paris is +1 → GMT = 6:00 PM – 1 hour = 5:00 PM GMT
> - Los Angeles is -8 → 5:00 PM – 8 hours =
9:00 AM
>
Answer: It is
9:00 AM in Los Angeles.
