Question
A flight controller determines that an airplane is 20.0 miles south of him. Half an hour later, the same plane is 35.0 miles northwest of him. The general direction of the plane's velocity is north of west. If the plane is flying with constant velocity, what is its velocity during this time? My question is, how do you know what the angles are? I drew the picture correctly, but in the solution, they have 45 degrees written on the picture. How did they know that was what it was?
