Question

if it is 10 am at 60° loguitude then ,explain what would be the local time at 120° east longitude​

Answer 1

Answer:

Earth rotates at 15 degrees of longitude per hour.

At 60E, the time is 1200 hrs. 30W is seperated by a longitude of 60+30 = 90 degrees.

Therefore, 90/15 = 6 hours.

Hence 30W longitude would be 6 hours behind 60E which is 0600 hrs.
