The airplane is flying at the speed of 500 mi/h at the altitude of one mile. Plane passes directly above the radar station at time t = 0.
(a) State distance s (in miles) between plane and radar station as the function of horizontal distance d (in miles) that the plane has flown.
(b) State d as the function of time t (in hours) that plane has flown.
(c) Use composition to state s as the function of t.
