Question

To avoid a storm, a passenger-jet pilot descended 0.18 mile in 0.4 minute. What was the plane's average

change of altitude per minute?

Answer 1

The plane's average change of altitude is 0.45 miles per minute

Explanation:

We have,

a passenger-jet pilot descended 0.18 mile in 0.4 minute.

It is required to find the plane's average change of altitude per minute.

It means we need to find the average speed. It can be calculated as :

`v=(0.18\ mile)/(0.4\ min)\\\\v=0.45\ mile/min`

So, the plane's average change of altitude is 0.45 miles per minute.
