A hot air balloon descends at a rate of 320 feet per minute for 3 minutes. Use integers to calculate and represent the balloon's total change in altitude.

5 answers

The total change in altitude of the balloon can be calculated by multiplying the rate of descent by the time it descends:

Total change in altitude = rate of descent x time

Total change in altitude = 320 feet/minute x 3 minutes

Total change in altitude = 960 feet

Therefore, the balloon descends 960 feet in total.

The volume of water in a reservoir decreases 21,000 cubic yards over a 3-month period. What is the average change in volume per month?
To find the average change in volume per month, we need to divide the total change in volume over the 3-month period by the number of months:

Average change in volume per month = total change in volume ÷ number of months

In this case, the total change in volume is a decrease of 21,000 cubic yards over a 3-month period, so:

Average change in volume per month = 21,000 cubic yards ÷ 3 months

Simplifying, we get:

Average change in volume per month = 7,000 cubic yards/month

Therefore, the average change in volume per month is a decrease of 7,000 cubic yards.
