Question

A hot air balloon went from an elevation of 4,064 feet to an elevation of 3,322 feet in 28 minutes. What

was its rate of descent?

Answer 1

The air balloon descends 26.5 feet per minute

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:

`\displaystyle R=(3,322-4,064)/(28)=(-742)/(28)=-26.5`

Thus the air balloon descends 26.5 feet per minute
