Question

Three minutes after a skydiver opens his parachute, he has descended 2,850 feet. After 5 minutes, he has descended 4,750 feet.

If he descends at a constant rate throughout, how many feet did he descend in one minute?

Answer 1

Calculate the slope

(2850-4750)/(3-5)= -1900/-2=950

So in one minute, he descended 950 feet
