This activity takes students through two problems:
After a water main break, a large building’s basement was flooded to the ceiling. The Denver department provided two pump trucks to pump the water out of the basement.
Because the Denver fire department was worried they could not pump the water out of the basement fast enough, they called in for reinforcements from the Iron Station fire department just 7 miles down the road. Two pump trucks responded to the call.
In these problems students are asked a series of questions to solve it given what the trucks pump.
