Time zone worksheet for students to practice calculating time differences using a world map.

To solve the time zone problems, we need to use the time zone map provided in the worksheet. Here's how to approach each question step by step:

Key Observations from the Map:

1. London is in the Greenwich Mean Time (GMT) zone, which is labeled as 0.
2. New York is in the Eastern Time Zone (ET), which is labeled as -5.
3. Moscow is in the Moscow Time Zone (MSK), which is labeled as +3.
4. Los Angeles is in the Pacific Time Zone (PT), which is labeled as -8.
5. Vancouver is also in the Pacific Time Zone (PT), which is labeled as -8.
6. Sydney is in the Australian Eastern Standard Time (AEST), which is labeled as +10.
7. Toronto is in the Eastern Time Zone (ET), which is labeled as -5.
8. Tokyo is in the Japan Standard Time (JST), which is labeled as +9.

Solution to Each Question:

#### 1. If it is noon in London, what time is it in New York?
- London is in the 0 time zone.
- New York is in the -5 time zone.
- To find the time in New York, subtract 5 hours from noon (12:00 PM).

- Answer: 7:00 AM

#### 2. If it is noon in New York, what time is it in London?
- New York is in the -5 time zone.
- London is in the 0 time zone.

#### 3. If it is noon in London, what time is it in Moscow?
- London is in the 0 time zone.
- Moscow is in the +3 time zone.
- To find the time in Moscow, add 3 hours to noon (12:00 PM).
- Noon + 3 hours = 3:00 PM
- Answer: 3:00 PM

#### 4. If it is noon in Moscow, what time is it in New York?
- Moscow is in the +3 time zone.
- New York is in the -5 time zone.
- The difference between Moscow and New York is 3 - (-5) = 8 hours.
- To find the time in New York, subtract 8 hours from noon (12:00 PM).
- Noon - 8 hours = 4:00 AM
- Answer: 4:00 AM

#### 5. If it is noon in New York, what time is it in Los Angeles?
- New York is in the -5 time zone.

- Answer: 9:00 AM

#### 6. If it is noon in Los Angeles, what time is it in Vancouver?
- Los Angeles is in the -8 time zone.
- Vancouver is also in the -8 time zone.
- Since both cities are in the same time zone, the time is the same.
- Answer: 12:00 PM

#### 7. If it is noon in Vancouver, what time is it in Sydney?
- Vancouver is in the -8 time zone.
- Sydney is in the +10 time zone.
- The difference between Vancouver and Sydney is 10 - (-8) = 18 hours.
- To find the time in Sydney, add 18 hours to noon (12:00 PM).
- Noon + 18 hours = 6:00 AM (next day)
- Answer: 6:00 AM (next day)

#### 8. If it is noon in Vancouver, what time is it in Toronto?
- Vancouver is in the -8 time zone.
- Toronto is in the -5 time zone.
