An Example:
A cricket match was to be held at Birmingham at 9 am local time. The position of Birmingham is
5" W. Calculate the time the viewers have to tune their television in Sydney 151'E.
Answer:
The local time at Birmingham is 9 am
The location of Birmingham is 5' W of Prime Meridian
The GMT would be 9:20 am 19:00hrs + (5°x4min) 9:00hrs + 20 min = 9:20 a.m.
Sydney is located at 151°E of Prime Meridian
At any point of time Sydney would be 151 x 4 - 604min 10hrs 4 min ahead of GMT
(Sydney is to the East of the Prime Meridian so local time would be ahead of GMT)
When it is 9:20 am GMT the local time at Sydney would be 19:24hrs or 7:24pm (9:20 + 10:04)
In order to watch the Birmingham match at Sydney the viewers would have to tune their televisions
at 7:24 p.m. local time.
