Question

A hot air balloon went from an elevation of 5,717 feet to an elevation of 3,388

feet in 34 minutes. What was its rate of descent?
The rate of the descent was
feet per minute.

Answer 1

68.5 feet per minute

Explanation:

rate of descent = feet / minute

First you need to find how many feet it has descended:

beginning altitude- ending altitude = total feet descended

5717 feet - 3388 feet = 2329 feet

To figure out the rate of decent we will divide

2329 feet / 34 minutes = 68.5 feet per minute

The hot air ballon descended 68.5 feet per minute for 34 minutes.
