Question

Calculate the local time at 75ᵒE when it is 6.30am at Greenwich fast​

Answer 1

Explanation:

Difference in Longitude = 0 + 75 = 75 degrees

Time taken for 1 degree longitude is 4 minutes.

Time taken for 75 degrees = 75 x 4 = 300 mins

To convert minutes to hours we should divide by 60, i.e. 300/60 = 3 hours.

Since, 75 degrees longitude is to the East we have to add Greenwich time = 6.30 + 5 = 11:30 a.m.
