Answer:

9 pm

Explanation:

If the local mean time at 45° W is 12:00 noon, what will be the local mean time at 90°E?

Solution:

The lines of longitude run from north to south, measuring distance from east to west of the prime meridian. The line of longitude are used to measure time between different locations.

Each 15° = 1 hour, 1° = 4 minutes

Change in longitude = 45° + 90° = 135°

Change in time = 135° * (1 hour per 15°) =  9 hours

Final destination time = initial time + change in time

Final destination time = 12 noon + 9 hours
