Question

If it is 4:00 p.m. at prime meridian , calculate the time at 22 degree east.​

Answer 1

Explanation:

Hypothetically ignoring the time zones of the world, the local time at longitude 60 degrees East will be 2 a.m and on the 22nd if the time at prime meridian is 10:00pm on the 21st. This is because the difference in degrees between longitudes 0 and 60 East is 60. But in every 4 minutes the earth rotates 1 degree. This implies that the earth takes 240 minutes to move 60 degrees. Note 240 minutes equals to 4 hours (240 divided by 60: 1hour =60 minutes). Therefore, 10:00pm (22:00 UTC), on 21st, plus 4 hours will be 2 a.m the following day, which is 22nd.
