The difference in longitude between  the Greenwich meridian (long,0\(^0\) ) and longitude 60\(^0\)E =60\(^0\)

For a longitude difference of 15\(^0\) , there will be a time difference of 1 hr Thus, for  60\(^0\) , the time difference will be 

  \(\frac{1hr}{15º} \times 60º \) =4hrs 

since we have traveled west of 60\(^0\)E to reach 0\(^0\) ( Greenwich meridians) 

We subtract time 

Thus .if it is 12 noon at long 60\(^0\)E the time at Greenwich meridian =14noon -4hrs =8.00 am
