During another part of its flight the balloon in exercise 10 had a change in elevation of -901 feet what was its rate of descent (exercise 10) a hot air balloon begins its descent at a rate of 22 1/2 per minute. how long will it take for the balloons elevation to change by -315 feet?

14 minutes

Step-by-step explanation:

velocity is defined as:

velocity = distance/time

The distance travelled by the balloon is 315 feet

Its velocity is 22.5 feet/min

Isolating time in the equation and replacing with data we get (dimensions are omitted):

time =  distance/velocity

time =  315/22.5

time = 14 minutes

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !
