A hot air balloon begins its descent at a rate of 22 1/2 feet per minute. How long will it take for the balloons elevation to change by -315 feet?
time = distance/speed, so
-315 / (-22.5) = ?
-7,087.5 I think
i dont da damn answer
To calculate the time it will take for the balloon's elevation to change by -315 feet, we can use 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.
First, let's convert the rate of descent to a decimal:
22 1/2 feet = 22.5 feet
Now, substitute the values into the formula:
Time = -315 feet / 22.5 feet per minute
Time = -14 minutes
Since the change in elevation is negative, indicating a descent, the answer will also be negative. Therefore, it will take approximately 14 minutes for the balloon's elevation to change by -315 feet.
