A plane (A) heading south at 120 mph and a plane (B) heading west at 600 mph are rlying tword the same point at the same altitude. Plane A is 100 miles from the point where the flight patterns intersect and plane B is 550 miles from there.

A) Find the parametric equation that model the motion of both planes
B) Find a formula for the distance between the planes as a function of time.
C) What is the min distance between the planes? When are the planes closest?

Thanks!!
