Question: An airplane is flying at a speed 350 mi/hf at an altitude of one mile and passes directly over a radar station at time t = 0.
(a) Express the horizontal distance (in miles) that the plane has flown as a function of t.
(b) Express the distance between the plane and the radar station as a function of d.
(c) Use composition to express as a function of t.
