Patricia has 4 barrels of 7 gallons each. All of them are empty, and there's only one faucet with a flow rate of 3.5 gallons per minute. How many minutes will it take to fill all 4 barrels?
If Patricia has 4 barrels and each barrel has 7 gallons, then in total she needs 4*7=<T>multiply(4, 7)=28 gallons
If the faucet can provide 3.5 gallons every minute, then she will need 28/3.5=<T>divide(28, 3.5)=8.0 minutes to fill all 4 barrels
