Tom has a 500 gallon pool. He is able to drain it at a rate of 15 gallons per minute.  if the pool still has 170 gallons of water remaining, how many minutes was the pool draining?
Step-by-step explanation: 500-170 means that he drained 330 gallons of water so 330 divided by 15 gallons a minute so you get 22 so it takes 22 minutes to have 170 gallons left in the pool
