Question

If it is 12 noon at Greenwich what is the time at 89 degrees east longitude

Answer 1

Answer:

So 1 degree will have a time difference of 24*60/360 = 4 minutes. Now if we move towards east from Greenwich, time difference will be added and vice-versa for west. 69 Deg means 69*4=276 min, East means time will be added. 12 Noon at Greenwich means 69 deg east will be 12 + 4 hr 36 min (276 min) = 4:36 pm.
