An aeroplane leaves town A (83°N, 155°W) to town B (40°N, 25°E) using the shortest route at a speed of 450 knots. (Take π = 3.142 and radius of the earth R = 6370km).
(a) (i) Calculate the distance between A and B in nautical miles.
(ii) Calculate the time taken to travel from town A to B
(b) From B, the plane flies westwards along the latitude to town C (40°N, 13°W). Calculate the distance BC in kilometers.
(c) From town C, the plane took off at 3:10 pm towards town D (10°N, 13°W), at the same speed. At what time did the plane land at D?
