Question 12

Latitude, Longitude and Time

The commentary of a football match which started at 1600 hours GMT in a town P(45°W) was heard in town Q at 2200 hours GMT. What is the longitude of Q?

  1. A.39°W
  2. B.45°E
  3. C.51°E
  4. D.90°W
  5. E.135°E
Show the answer and explanation

Answer: B (45°E)

Explanation

Taking the times as local times: P at 45°W is 3 hours behind Greenwich, so the match began at 1900 GMT; Q's time of 2200 is 3 hours ahead of GMT, and 3 × 15° = 45°E.
