Question

A hang glider flew to an altitude of 10,000 feet. Fifteen minutes later, it's altitude was 7,000 feet. What was the average change in elevation per minute?

Answer 1

10000-7000=3000
3000/15= 200
The average change in elevation per minute was 200 feet

Answer 2

Answer: The average change in elevation per minute is 200 feet per minute.

Explanation:

Since we have given that

Altitude at which a hang glider flew = 10,000 feet

After 15 minutes,

Altitude becomes = 7,000 feet

So, Average change in elevation per minute becomes

`(New-Old)/(Time)\\\\=(10000-7000)/(15)\\\\=(3000)/(15)\\\\=200\ ft/min`

Hence, the average change in elevation per minute is 200 feet per minute.
