During a recent trip to Scotland, I filled my petrol tank to the top, a total of 10 gallons. I travelled at 60 mph up the motorway and I knew that I could average 40 miles per gallon. However, the moment I started, my petrol tank developed a leak and four hours later I ground to a halt having run out of petrol. How much petrol had I lost through the leak?

I had lost 4 gallons in total.

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.
