Could anyone give me the solution and the method for this question?
John was playing with a remote control plane which flew with constant speed. He wanted to fly the plane from A to B, 500 m due north. Due to a steady wind blowing due south, the plane was at C, which was 400 m from B after 25 seconds. Given that the wind was blowing at a speed of 6m/s, find the speed of the plane in still air.
