The positions of airport P and Q are(60°N, 45°W) and (60°N, K°E) respectively. It takes a plane 5 hours to travel due eat from P to Q at an average speed of 600 knots. By taking R = 6370 km and#pi# = #22/7#a) Calculate the value of Kb) The local time at P is 10.45am. What is the local time at Q when the plane reaches there?(Give time in 12 hour clock)c) Find the distance PQ measured along a circleof latitude to the nearest Km.
