Question

A parachutist descends 95 feet in 5 seconds. Express the rate of the parachutists change in height as a unit rate?

Answer 1

Given that,

The decend rate = r = 95 feet in 5 seconds.

We can write this like that,

In 5 seconds, a parachutist descends = 95 feet

In 1 second, a parachutist descends = 95/5 feet

=> 19.

Hence, the rate of the parachutists change in height as a unit rate is 19 feet per second.
