A flight controller determines that an airplane is 20.0 south of him. Half an hour later, the same plane is 46.0 northwest of him.
If the plane is flying with constant velocity, what is the direction of its velocity during this time?
What is the magnitude of its velocity during this time?

If the controller is at (0,0) the plane moved from (0,-20) to (-32.53,32.53)
The distance is 61.79
Assuming the distances are in km, that would make the speed 123.58 km/hr
The direction is θ such that
tanθ = 52.53/-32.53
