Title: Duck In Pond
Post by twitceh on Feb 20^th, 2007, 5:23pm

A duck is in a circular pond with a menacing cat outside. 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.

The original problem is in the riddle page of this site:
http://www.ocf.berkeley.edu/~wwu/riddles/hard.shtml

And there are two long threads about it too:

The first I could not find, the second is here:

For what it's worth: the original thread (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_hard;action=display;num=1028614054), and the first followup (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_hard;action=display;num=1046187731).

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