Question

During a flood, James used two pumps to get the water out of his

basement. The big pump moves 3 gallons of water per minute. The
small pump moves 4 gallons in 5 minutes. How many more gallons
does the big pump move than the small pump after 10 minutes?

Answer 1

The big pump moves 22 more gallons in 10mins

Explanation:

The total the big pump moves is 30 gallons in 10mins because 3x10 = 30

The small pump moves 8 gallons in 10mins becuase 4x2= 8

Its asking for how many more so 30 - 8 = 22 More gallons
