Aubriella is pouring water into a 50-gallon fish tank at the rate of 1 gallon every 20 seconds. How many more gallons will she have to pour into the tank to fill the tank if she poured water into the fish tank for 6 minutes? Let's think first. Chain of thought:
When she poured water into the gallon for 6 minutes, the total time in seconds she took is 6 minutes * 60 seconds / minute = 360 seconds. If in 20 seconds she poured 1 gallon of water into the tank, in 360 seconds, she poured 360 seconds / 20 seconds / gallon = 18 gallons of water into the tank. Aubriella will have to pour 50 gallons - 18 gallons = 32 more gallons into the tank to fill the tank.
Therefore, the answer is 32.
