Billy And Virginia
Billy started out on a trip from Virginia with a full tank of fuel, 12 gallons exactly. However, the moment Billy started out, the fuel tank sprung a leak. Billy travelled at 50 mph until he ran out of fuel exactly 4 hours later. Billy knows that the car does 25 miles for each gallon. How much fuel had Billy lost through the hole?
