Q: A place is located at 45°N latitude and 90°W longitude. What is the time at this location when it is 3:00 PM GMT? (2019)

Solution: The time difference is (90° / 15°) = 6 hours. Therefore, it is 3:00 PM - 6 hours = 9:00 AM.

Steps: 7

Step 1: Understand that GMT (Greenwich Mean Time) is the time at the Prime Meridian (0° longitude).
Step 2: Identify the location's longitude, which is 90°W.
Step 3: Calculate the time difference from GMT. Each 15° of longitude represents 1 hour of time difference.
Step 4: Since the location is at 90°W, divide 90° by 15° to find the time difference: 90° / 15° = 6 hours.
Step 5: Determine if the location is ahead or behind GMT. Since it is 90°W, it is behind GMT.
Step 6: Subtract the time difference from GMT time. If it is 3:00 PM GMT, then subtract 6 hours: 3:00 PM - 6 hours = 9:00 AM.
Step 7: Conclude that the time at the location is 9:00 AM.
