6 cats kill 6 rats in 6 minutes .how many cats will be
needed to kill 100 rats in 50 minutes?

Answer Posted / michael

If we assume that 1 solo cat can kill 1 rat in 6 min and they don't start hunting together to kill rats faster & we are not using cats part of the time, we can't meet the criteria exactly.
Example:
1) At minute 48, 12 cats would have killed 96 rats. With the remaining 2 min, there isn't enough time to kill another set of rats.
2) If we use 13 cats we can have 104 rats killed with 2 minutes remaining.

We can't get exactly 100 rats in 50 min but we can get close.
