Question

A tank currently holds 5 gallons of water.it is 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

Answer:

16 minutes

Step-by-step explanation:

Because the tank already holds 5 gallons of water, you only need to find the number of minutes to fill 4 gallons of water.

Because it fills at a rate of 1/4 gallons a minute, it takes 4 minutes per gallon of water.

Since we are dealing with 4 gallons of water to be filled, we multiply 4 · 4 to get the number of minutes.

4 · 4 = 16

16 minutes
