A hot air ballon begins its descent at a rate of 22 1/2 feet per minute. How long will it take for the balloon's elevation
to change by -315 feet?

Respuesta :

The descent of the balloon would take 14 minutes
To find the answer to this problem, take the elevation change (315) and then divide it by the rate of descent (22.5)
It will take 14 mins since 315/22.5=14 hoped this helps
