Puzzle ZNFV 



??

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?

Answer
I had lost 4 gallons in total.

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.
