During a recent trip to Scotland, I filled my car's 10 gallon fuel tank to the very top.
I travelled at 60 mph up the motorway, and I knew that I averaged exactly 40 miles per gallon.
However, the moment I started, my fuel tank developed a leak, and four hours later I came to a complete stop as I'd run out of fuel!
How much fuel did I lose through the leak?

Answer
I had lost 4 gallons of fuel.
Reasoning
I travelled at 60mph for 4 hours, which is 240 miles.
At 40 miles per gallon this used 6 gallons, which meant the remaining 4 gallons were lost.
