Question

A hot air balloon rises 350 feet in 5 minutes

What is the balloon’s ascent rate in feet per minute?

How long did it take the balloon to rise 1470ft?

Estimate how high the balloon will ascend after 27 minutes.

Answer 1

70 feet per minute.

21 minutes

1890 feet

Answer 2

Explanation:

(350 ft) / (5 min) = 70 ft/min

(1470 ft) / (70 ft/min) = 21 min

(70 ft/min) * (27 min) = 1890 ft
