Question

A skydiver jumped out of a plane and

descended 0.66 miles in 1.5 minutes.
What was the skydiver's average change
of altitude per minute?

Answer 1

Answer:
`0.44 mi/min`

Explanation:

We are asked to find the "skydiver's average change of altitude per minute", this means we have to find the variation of the skydiver's distance in a given time. This is its velocity, which is given by:

`V=(\Delta d)/(\Delta t)`

Where:

`V` is the skydiver's velocity

`\Delta d=0.66 mi` is the distance the skydiver has descended

`\Delta t=1.5 min` is the time in which the skydiver has descended its distance

Solving:

`V=(0.66 mi)/(1.5 min)`

`V=0.44 mi/min` This is the skydiver's average change of altitude per minute
