Puzzle 4
I started a journey to my Aunt's yesterday with a full tank of gasoline, 10 gallons, but at that exact moment my gasoline tank sprang a leak.
I managed to drive 50 miles, in exactly one hour, before coming to a complete stop with an empty tank.
I know that the car manages 25 miles per gallon.
How quickly was I losing gasoline?

Hint
How many gallons did the journey use?
Answer
8 gallons an hour.
Reasoning
I travelled 50 miles in one hour, at 25 miles per gallon this must have used 2 gallons.
So I must have lost the other 8 gallons through the hole.
