Out of gas. (Posted on 2007-09-22) Difficulty: 2 of 5
A man runs his car out of gas thereby completely emptying his 16 gallon tank. He only has a 3, a 6, and a 11 gallon container (and fortunately a wagon to carry the containers in) in his trunk. He has nothing else in which he can carry gas. He walks a few miles to a gas station, and as luck would have it the gauge on the pump is broken so he can not use that to measure the fuel. He is in a pretty remote area with only one gas station for miles. Gas costs $3.099, and he only has a $50. Using only the containers provided, and only walking once to and from the gas station, how can he get exactly 16 gallons of gas into his car?

I think it would be easier to just fill the 3 gallon container, or even put just about a gallon into it. Much easier to carry. And at most 25 pounds you do not need the wagon, although it might be easier. With only a gallon it will be about 8.3 lbs. That indeed was my intended solution.
