making linear equation from word problem

At low altitudes, the altitude of a parachute and time in the air are linearly related. A jump at 2,880 ft use the US army T-10 parachute system last 120 sec.

(A) find a linear model relating altitude a (in feet) and time in the air t (in seconds)

(B) the rate of descent is the speed at which the jumper falls. What is the rate of descent for a T-10 system?
