Puzzle 96
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?

Hint
How far did I travel?
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.
