I am doing a homework assignment for my General Engineering class and am really frustrated because I can't get it, and I remember doing this sort of problem in high school, but forget how to do it. Here it is A plane flies (in still air) at 250 mi/hr. On Monday morning the plane leaves point A and flies due East for one hour and then flies due south for one hour to arrive at B. Throughout the wind velocity is 50 mi/hr to the east a) What is the distance from B to A? b) What is the heading (the direction the plane must point in) that the plane must fly to return to B? c) How long would it take for the return flight? I drew a nice little picture and figured out when it is flying east it will be flying 300 mi/hr with the wind, but I forget what to do when he is flying south and the wind is east. Any help would be greatly appreciated!
