At what rate was the skydiver descending, in feet per minute?
feet per minute

Answer 1

if you look at it as a graph, you’re basically finding the slope. equation for slope is
b= y2-y1
———- so b= 5280-3168 2112
x2-x1 —————— = ——— = 1056
5-3 2


answer: 1056 feet. hope this helps :)

Answer 2

1,056 feet per minute
