The cat runs four times as fast as the duck can swim, but cannot enter the water. Can the duck get to the perimeter of the pond without the cat being on top of him?   Does anyone have any conclusive solutions for this?   Sorry edited. « Last Edit: Feb 21st, 2007, 12:38am by twitceh » IP Logged ThudnBlunder wu::riddles Moderator Uberpuzzler The dewdrop slides into the shining Sea     Gender: Posts: 4489 Re: Dog and You   « Reply #1 on: Feb 20th, 2007, 6:06pm » Quote Modify on Feb 20th, 2007, 5:23pm, twitceh wrote: Does anyone have any solutions for this?

IP Logged You can only believe i what you can prove, and since you have nothing proven to cmpare to, you can believe in nothing. I have ~50 posts to hack a "R" into a "D". Which one?

But unlike in the riddle the ducks are 3D animals (moving 3D, i.e. can fly), so they are still safe and cats still must catch mice if they want to eat.
