Question

An airplane has a speed 590 km/h . If a wind begins blowing from the southwest at a speed of 94.9 km/h (average). In what direction should the pilot aim the plane so that it will fly due south?

Answer 1

you want to fly west to counteract the wind trying to blow you east.

ArcTan(94.9/590) W of S might be a good course. Draw the diagram and see.
