Answer 2

Answer:

Explanation:

given,greenwich =0 degree

we know that, the suns rays take 4 minutes to cross each longitude

1)69°E=the difference between 0 longitude to 69 longitude=69 longitude

time difference=69×4=276min

276min=4hours  36 min

time=12noon +4 hrs 36min

      =4:36

2)30°W=the difference between 0 longitude to 30 longitude=30 longitude

time difference=30×4=120min

120min=2hours

time=12noon -2 hrs (WEST)

      =10:00AM

3)12°E=the difference between 0 longitude to 12 longitude=12 longitude

time difference=12×4=48min

48min=48MIN

time=12noon +48 min (EAST)

      =12:48 PM
