The difference in longitude between the Greenwich meridian (long,00 ) and longitude 600E =600
For a longitude difference of 150 , there will be a time difference of 1 hr Thus, for 600 , the time difference will be
1hr15º×60º =4hrs
since we have traveled west of 600E to reach 00 ( Greenwich meridians)
We subtract time
Thus .if it is 12 noon at long 600E the time at Greenwich meridian =14noon -4hrs =8.00 am
