A bathtub that hols 32 gallons of water contains 12 gallons of water you begin filling it and after 5 minutes the tub is full

Okay. I am guessing that you are asking for the amount of water poured per minute. The bathtub already holds 12 gallons and 32 - 12 is 20. The tub is full in 5 minutes. Let’s divide. 20/5 is 4. There are 4 gallons of water filled in the tub per minute.
