View Full Version : Luna's Jalopy

After visiting my Great Aunt Luna, I travelled home in her old jalopy. The car was old and battered, it had a leak from the petrol tank, and I was stuck in second gear.

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.

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.

Just as I arrived home, the car stopped because it had run out of fuel and I had only just made it.


How far was it from Luna's to my home?

200 miles for ten gallons

But as you are losing half a gallon each hour you are only get 10 mpg instead of 20.

So 100/30=3.3333

3hours 20 mins?

Just taking a guess.
5 hours.

30 miles per hour = 1.5 gals plus .5 gal. loss = 2 gals. per hour.

10gals by 2gals/hr = 5 hrs. and 150 miles??
