Final answer:
The number of gallons of water that come out of the faucet in t minutes can be found by multiplying the flow rate by t.
Step-by-step explanation:
The flow rate of water coming out of the faucet can be calculated by dividing the volume of water by the time it takes to flow out. In this case, the volume of water that comes out in 2 minutes is 7 gallons. So, the flow rate can be calculated as:
Flow Rate = Volume/Time = 7 gallons/2 minutes = 3.5 gallons/minute
Therefore, the number of gallons of water that come out of the faucet in t minutes can be found by multiplying the flow rate by t. So, the formula to calculate the number of gallons is:
Number of Gallons = Flow Rate * Time
