Educational worksheet on world time zones and time difference calculations.

To solve these problems, we need to look at the time zones on the map and count the difference in hours between the cities.

Part 1: It is 10:00 am in Moscow.

1. What time is it in Madrid?
* Look at the map. Moscow is in the +3 time zone. Madrid is in the +1 time zone.
* The difference is 2 hours. Since Madrid is to the left (west), it is earlier.
* 10:00 am minus 2 hours = 8:00 am.

2. What time is it in Los Angeles?
* Look at the map. Moscow is in the +3 time zone. Los Angeles is in the -8 time zone.
* The difference is 11 hours (3 + 8). Since Los Angeles is to the left (west), it is earlier.
* 10:00 am minus 11 hours. Going back 10 hours from 10 am takes us to midnight (12 am). Going back 1 more hour takes us to 11 pm the previous day.

3. What time is it in Hong Kong?
* Look at the map. Moscow is in the +3 time zone. Hong Kong is in the +8 time zone.
* The difference is 5 hours (8 - 3). Since Hong Kong is to the right (east), it is later.
* 10:00 am plus 5 hours = 3:00 pm.

Part 2: It is 12 o'clock GMT (Greenwich Mean Time).
*Note: GMT is the 0 time zone.*

4. What time is it in Tokyo?
* Look at the map. Tokyo is in the +9 time zone.
* The difference is 9 hours. Since Tokyo is to the right (east), it is later.
* 12:00 pm (noon) plus 9 hours = 9:00 pm.

5. What time is it in Denver?
* Look at the map. Denver is in the -7 time zone.
* The difference is 7 hours. Since Denver is to the left (west), it is earlier.
* 12:00 pm minus 7 hours = 5:00 am.

Part 3: It is 7:00 pm in New York.

6. What time is it in Berlin?
* Look at the map. New York is in the -5 time zone. Berlin is in the +1 time zone.
* The difference is 6 hours (5 + 1). Since Berlin is to the right (east), it is later.
* 7:00 pm plus 6 hours = 1:00 am (the next day).

7. What time is it in Rome?
* Look at the map. New York is in the -5 time zone. Rome is in the +1 time zone (same as Berlin).
* The difference is 6 hours. Since Rome is to the right (east), it is later.
* 7:00 pm plus 6 hours = 1:00 am (the next day).

8. What time is it in Toronto?
* Look at the map. New York is in the -5 time zone. Toronto is also in the -5 time zone.
* There is no time difference.
* The time is 7:00 pm.

9. What time is it in Bangkok?
* Look at the map. New York is in the -5 time zone. Bangkok is in the +7 time zone.
* The difference is 12 hours (5 + 7). Since Bangkok is to the right (east), it is later.
* 7:00 pm plus 12 hours = 7:00 am (the next day).

10. What time is it in your town?
* This depends on where you live. You would need to find your town on the map, see its time zone number, and calculate the difference from New York's -5 zone.
