Question

. If it is 12 noon at Greenwich, calculate the local time of the places located on the following longitudes: 79°E, 20°W?

Answer 1

Answer:

360° covers in 24 hrs

then 1° in = 4 minute

1.) 79°E = 79x4= 316 minutes= 5hr:27 minute

Time at place one = 12+5:27= 17 :20 P.M

2.) 20° W = 20x4= 80 minutes= 1hr: 20 minute

Time at place two= 12-1:20= 11:20 A.M
