The car was old and battered, it had a leak from the petrol tank, and I was stuck in second gear. <br /> <br /> This meant that I could only travel along at a steady 30 miles per hour and managed a paltry 20 miles per gallon of fuel. <br /> <br /> At the start of the journey I had placed exactly 10 gallons of fuel into the tank. I knew though, that the fuel tank lost fuel at the rate of half a gallon per hour. <br /> <br /> Just as I arrived home, the car stopped because it had run out of fuel and I had only just made it. <br /> <br /> <br /> How far was it from my Great Aunt's to my home?
