The difference in longitude between the Greenwich meridian (long,00^{0}0 ) and longitude 600^{0}0E =600^{0}0
For a longitude difference of 150^{0}0 , there will be a time difference of 1 hr Thus, for 600^{0}0 , the time difference will be
1 hr15∘×60∘\; \frac{1\,\text{hr}}{15^{\circ}} \times 60^{\circ}15∘1hr×60∘ =4hrs
since we have traveled west of 600^{0}0E to reach 00^{0}0 ( Greenwich meridians)
We subtract time
Thus .if it is 12 noon at long 600^{0}0E the time at Greenwich meridian =14noon -4hrs =8.00 am
