two airports A and B are such that B is 500 km due east of A. Two planes P and Q take off from A and B respectively at the same time. Plane P flies at 360 km/hr on a bearing of 030. Plane Q flies at 240km/hr on a bearing of 315. The two planes land after 90 minutes. Using a scale of 1: 10000000; sho the position of the two planes after 90 minutes; find the distance between the two planes after 90 minutes; find the bearing of plane Q from plane P after 90 minutes
