Assuming the same pane speeds as In Example 2, how fast is the distance between the planes changing if x = 60 mi and y = 75 mi?
Example 2 Converging Airplanes
Two small planes approach an airport, one flying due west a: 120 mi/hr and the other flying due north at 150 mi/hr. Assuming they fly at the same constant elevation, how fast is the distance between the planes changing when the westbound plane is 180 miles from the airport and the northbound plane is 225 miles from the airport?
