conversations.value: I'm completely lost with this math problem: 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?
  Can you give me a hand?

conversations.value: If Patricia has 4 barrels and each barrel has 7 gallons, then in total she needs 4*7=28 gallons
  If the faucet can provide 3.5 gallons every minute, then she will need 28/3.5=8 minutes to fill all 4 barrels
