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, 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?
8 gallons an hour.
Since I was travelled 50 miles in the one hour, this must have used 2 gallons (at 25 miles per gallon).
So I must have lost the other 8 gallons through the hole.
