An airplane pilot sets a compass course due west and maintains an airspeed of 225 km/h. After flying for a time of 0.510 h, she finds herself over a town a distance 123 km west and a distance 19 km south of her starting point. Find the magnitude of the wind velocity.

Find the direction of the wind velocity.

If the wind velocity is 44 km/h due south, in what direction should the pilot set her course to travel due west? Use the same airspeed of 225 km/h .
