# Calculating wind speed with respect to an airplane

#### kvandeaver

1. Homework Statement
An airplane pilot sets a compass course due west and maintains an airspeed of 220 km/hr. After flying for .5 hr, she finds herself over a town 120 km west and 20 km south of her starting point. Find the wind velocity (magnitude and direction).

2. Homework Equations

3. The Attempt at a Solution
I have attempted setting up the diagram and finding the vector components of each velocity, and then using right triangles to find the magnitudes, but I keep getting the wrong answer. I have no idea how to go about doing this problem.
