Question

If the time of a place located on ${165}^{o}E$ meridian is 11:00 pm on Sunday, what would be the time at the place located on ${165}^{o}W$ meridian?

• A. 1:00 pm on Sunday
• B. 12:00 noon on Sunday
• C. 1:00 am on Sunday
• D. 11:00 pm on Sunday

Answer 1

Answer: (C)

1:00 am on Sunday

A difference of 15 degrees in longitude accounts for 1 hour of time difference. In this case, total difference in longitude is 330 degrees which means that total time difference between the two places would be 330/15 which is equal to 22 hours. Thus the time at the place at 165 degrees West would be 1 AM (Sunday).
