It is empty a gallon every two and a half minutes so 2 1/2x x=gallons of water

it will take 12 1/2 minutes to completely empty since it takes 2 1/2 minutes per gallon.

the tank was full 7 1/2 minutes before Jada arrived. 10-7= 3 so it emptied 3 gallons before Jada arrived. It takes 2 1/2 mins for a gallon to empty so 2 1/2 times 3 equals 7 1/2 mins
