    If 3 rats eat 3 cats in 1 minute then 1 rat eats 1 cat in 1 minute. At that rate 1 rat would eat 30 cats in 30 minutes. Mind you it would have to be a pretty big rat ! !

  • Are you sure that's not backwards?  Whatever.  A rat can eat 1 cat per minute

    30 rats will eat 30 cats per minute for 30 minutes

    30 cats/minute * 30 minutes = 900 cats

    900
