Two planes P and Q depart from airports A and B respectively. A and B are 500km apart, B is east of A. Plane P departs A at 360 km/h on a bearing of 030°. Plane Q departs B at 240 km/h on a bearing of

Here's the solution to the problem:

Problem Analysis:

• Airport A and B are 500 km apart, with B due East of A.
• Plane P starts from A, speed 360 km/h, bearing 030°.
• Plane Q starts from B, speed 240 km/h, bearing 315°.
• Both planes fly for 90 minutes.
• We need to draw their positions on a scale and find the distance between them.
