Plane A is 40 mi south and 100 mi east of Plane B. Plane A is flying 2 miles west for every mile it flies north, while Plane B is flying 3 mi east for every mile it flies south.

a. Where do their paths cross?

b. Which plane must fly farther?

c. What ratio of the speed of Plane B to the speed of Plane A would
produce a midair collision?
