Question

A hot air balloon begins it dissent at a rate of 22 to 1/2 ft. per minute how long will it take for the balloons elevation to change by -315 feet?

Answer 1

In 14 minutes.

Explanation:

At the rate of 22 and
`(1)/(2)` feet per minute, a hot air balloon is going down.

Therefore, the balloon dissents
`22(1)/(2) = (45)/(2)` feet per minute.

Therefore, the balloon will dissent 315 feet i.e. there will be a change of elevation by - 315 feet in
`(315)/((45)/(2) ) = (315 * 2)/(45) = 14` minutes. (Answer)
