Question

A tank currently holds 5 gallons of water, it being filled at the rate of 1/4 gallon per minute. How long will it take for the tank to hold 9 gallons of water?

Answer 1

it will take 16 minutes

Explanation:

Its already filled 5 gallons. if it's 1/4 per minute, then in 4 minutes 1 gallon will be filled. that means in 16 minutes it will be filled 9 gallons because 4 minutes x 4 is 16 minutes and 1 gallon times 4 is 4 gallons and 4 gallons + 5 gallons is 9 gallons ur welcome
