Compute each part of following question given below:
Question: An airplane pilot sets a compass course due west and maintains an airspeed of 217km/h. After flying for a time of 0.470h, she finds herself over a town a distance 125km west and a distance 21km south of her starting point.
Part A: Find the magnitude of the wind velocity.
Part B: Find the direction of the wind velocity.
Part C: If the wind velocity is 43km/h due south, in what direction should the pilot set her course to travel due west? Use the same airspeed of 217km/h.
Please help for the above question, completely confused!! Show each steps if possible, Thanks.
