Question

A hot air balloon went from an elevation of 5,275 feet to an elevation of 3,128 feet in

38 minutes. What was its rate of descent?



The rate of the descent was_____ feet per minute.

Answer 1

0.942 ft/s

Explanation:

The rate of descent is the rate at which the hot air balloon is descending, that is, how fast it is descending.

We calculate this by finding how far it has moved and then dividing it by the time it took it to descend.

It moved from 5275 ft to 3128 ft. The displacement is:

5275 - 3128 = 2147 ft

The time taken is 38 minutes. In seconds, it is:

38 * 60 = 2280 seconds.

Therefore, the rate of descent is:

2147 / 2280 = 0.942 ft/s
