A car and a small plane travel from the same starting point to the same destination by diﬀerent routes. The plane travels in a straight line for 65 minutes at an average speed of 250mph (1m/s = 2.24mph). The car travels 370 miles along a route that goes due south and then due west, further west than south. If the plane travelled in a straight line, at what angle south of west did it travel? I know I have to use the pythagorean theorem (at least i think so) but I just cant get it set up right.
