A hot air balloon is at an altitude of 100 1/5 yards. The balloon's altitude decreases

by 10 4/5 yards every minute. Determine the

number of minutes it will take the balloon to reach an altitude of 57 yards.

It will take 4 minutes for the balloon to reach an altitude of 57 yards.

Step-by-step explanation:

Initial altitude:

100 1/5 yards = 100 + 0.2 = 100.2 yards.

Decrease per minute:

10 4/5 yards = 10 + 0.8 = 10.8 yards.

So, after t minutes, the height of the ballon is given by:

Number of minutes it will take the balloon to reach an altitude of 57 yards.

This is t for which . So

It will take 4 minutes for the balloon to reach an altitude of 57 yards.

step-by-step explanation:

8+13=21

21+8=29

29+6=35
