 A Better Mousetrap (Posted on 2004-01-20)
The following question was asked on a math test:
If 6 cats kill 6 rats in 6 minutes, how many will be needed to kill 100 rats in 50 minutes?

Ryan answered 12, Stefanie said 13, and Tom put down 14 for his answer. After looking at their work, the teacher decided to give all three students credit.

What were the arguments that each student made?

Cats kill to eat. A rat is a big meal for a cat. Cats always sleep for hours after a big meal. 6 cats might kill 6 rats in 6 minutes but it would be hours at least before any of the 6 killed again. To kill 100 rats in 50 minutes you need 100 cats.

Cats sometimes kill for fun but they also sometimes share prey. All the answers are too low!
