17.An aero plane that moves at a constant speed of 600 knots flies from town A (14°N, 30°W) southwards to town B (XºS, 30°W) taking 3hrs. It then changes direction and flies along latitude to town C (XºS, 60°E). Given = 3.142 and radius of the earth R = 6370 km (a) Calculate (i) The value of X (3 marks) (ii) The distance between town B and town C along the parallel of latitude in km. (2 marks) (b)D is an airport situated at (5°N, 120°W), calculate (i) The time the aeroplane would take to fly from C to D following a great circle through the South Pole. (3 marks) (ii) The local time at D when the local time at A is 12.20 pm (2 marks) 17.An aero plane that moves at a constant speed of 600 knots flies from town A (14°N, 30°W) southwards to town B (XºS, 30°W) taking 3hrs.
