Answer:
"total change in altitude for all 4 balloons is 8260 feet"
Step-by-step explanation:
295 feet per minute, so in 7 minutes:
Descend (for 7 minutes) = 295 * 7 = 2065 feet
This is for a <em>single balloon.</em>
<em />
So for 4 balloons, this would be:
2065 * 4 = 8260 feet in total
So, total change in altitude for all 4 balloons is 8260 feet
The answer is .65 gallons. Just multiply 1.5 times 7 and convert it to gallons.
1, 2, 7, 14.
