Puzzle 1
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?

Hint
How far did I travel, and how much fuel did this use?
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.

Hint
Look for the question.
Answer
N.
Reasoning
Starting with the first letter and taking every other letter gives: TO BE OR NOT TO BE TH
Starting with the second letter and taking every other letter gives: AT IS THE QUESTIO
Combining gives: TO BE OR NOT TO BE THAT IS THE QUESTIO, and the last letter of QUESTION is missing.
