Cats and Sausages
I like pets, but, for various reasons, I can’t have one. So I flirt with other people’s pets. There is a black cat across the road who likes sitting in my driveway. So I had to buy a new car with a backup camera to make sure the cat is safe. As you can imagine, I couldn’t skip this problem about cats posted by Konstantin Knop on Facebook.
Puzzle. One cat eats one stick of sausage in 27 minutes. You have four identical sticks of sausage and five cats. Using only the cats and the sausages, measure exactly one minute.
All the cats eat at the same constant rate, and all the sausage sticks are identical. You may measure time intervals only between moments when cats finish sausage sticks. At each such moment, you may redistribute the cats among the remaining sausage sticks.
