Question

. THE TIME AT 20 DEGREES EAST LONGITUDE IS 4:00 A.M. FIND THE TIME AT 80 DEGREES EAST LONGITUDE.

Answer 1

The time at 80 degree east longitude is 12 midnight.

Explanation:

• Lets say the 20 degree east longitude is = Place A
• The 80 degree east longitude is  = Place B
• Total number of longitudes =  ( 80 - 20 ) = 60
• Time difference between the longitudes = 60 x 4 = 240
• Convert it into hours = 240 / 60 = 4 hours
• Since it is 4 am in place A, and the place B is to the left of the place A we will subtract time.
• 4 a.m - 4 = 12 midnight (00:00)
