A hot air balloon 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?

During another part of its flight, the balloon had a change in elevation of
-901 feet. What was its rate of descent?

**Write and solve both equations.
THANK YOU!

time = distance/rate = 315/22.5 = 14

missing information for the second question,
all you gave is the distance

To find the time it will take for the balloon's elevation to change by -315 feet, we can set up an equation using the formula:

Time = Change in elevation / Rate of descent

In this case, the change in elevation is -315 feet, and the rate of descent is 22 1/2 feet per minute.

Time = -315 feet / (22 1/2 feet per minute)

To divide by a fraction, we can multiply by the reciprocal of the fraction:

Time = -315 feet / (45/2 feet per minute)

To divide by a fraction, we can multiply by the reciprocal:

Time = -315 feet * (2/45 minutes per foot)

Now, multiply the numerator and denominator separately:

Time = (-315 * 2) / (45)

Time = -630 / 45

Time = -14 minutes

So, it will take the balloon 14 minutes to change its elevation by -315 feet.

To find the rate of descent when the balloon had a change in elevation of -901 feet, we can rearrange the formula:

Rate of descent = Change in elevation / Time

In this case, the change in elevation is -901 feet, and we need to know the time it took for this change to occur.

Rate of descent = -901 feet / Time

Since we don't have the time provided in this question, we can't calculate the exact rate of descent.
