Teresa pumped 14 gallons of water out of her pool.This was done over a period of 2 minutes at a constant rate.What was the change in the amount of water in the pool each minute?

The rate of pumping water out of the pool is 

 

r = (14 gal) / (2 min) = 7 gal/min

 

That means that each minute, the amount of water in the pool dropped by 7 gal.
