Explanation:
The local time at Birmingham is 9 am.
The location of Birmingham is 5° W of Prime Meridian.
The GMT would be 9:20 a.m.
[9.00hrs + (5° × 4min) = 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 × 4 = 604 min = 10 hrs 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 a.m. GMT the local time at Sydney would be (9:20 + 10:04) 19:24 hrs or 7:24 p.m.
in order to watch the Birmingham match at Sydney the viewers would have to tune their televisions at 7:24 p.m. local time.
