[johnthefoxx]

if 5 cats can catch 5 mice in 5 minutes how many cats will you need to catch 100 mice in 100 minutes

5?

5.. The number of mice increases by x20 but so does the time, and they cancel each other out.

5. Each single cat can catch a mouse every 5 minutes so 5 will catch 20 each in 100 mins.

When I saw the question title I was expecting to see the old chestnut about "7 people on a bus with 7 bags each containing 7 cats and each cat had 7 kittens.. how many legs.."
