Answer:
The air balloon descends 26.5 feet per minute
Step-by-step explanation:
Rate of Change
The rate of change is a measure that compares two quantities, usually to know how one variable changes in time.
The hot air balloon was 4,064 feet high and, 28 minutes later, it went to 3,322 feet. We can calculate the rate of descent R by dividing the change of elevation over time:
[tex]\displaystyle R=\frac{3,322-4,064}{28}=\frac{-742}{28}=-26.5[/tex]
Thus the air balloon descends 26.5 feet per minute
