Question

A hot air balloon is at an altitude of 10015 yards. The balloon's altitude decreases by 1045 yards every minute. Which equation can be used to determine the number of minutes m it will take the balloon to reach an altitude of 57 yards?

Answer 1

It will take approximately 9 minutes for the balloon to reach an altitude of 57 yards.

Step-by-step explanation:

To determine the number of minutes it will take for the hot air balloon to reach an altitude of 57 yards, we can use the equation:
m = (10015 - 57) / (-1045)

Simplifying the equation:
m = 9458 / -1045

Dividing 9458 by -1045 gives us:
m ≈ -9.06

Since we cannot have a negative number of minutes, we can round -9.06 up to -9. Therefore, it will take approximately 9 minutes for the balloon to reach an altitude of 57 yards.
