Answer 2

Answer:

30*4=120 min= 2hours

ans=11:30

Explanation:

The earth rotates 10 in four minute, so we will divide the longitude by 30. As the earth rotates from west to east, those places that lie east of Greenwich are ahead than the places that lie to the west of Greenwich. Hence, we will add one hour to the given time at the Prime meridian.

Thus, the time at 30 degree East will be 11:30Am.
