    12 days.


    Takes him 11 days to net 11 inches.  On the 12th day, he advances 3 inches and gets out before falling back.


    Yes, it's final:  12.  (11 days would only get the worm to the top of the hole but not over).

    No, your answer is wrong.

    I'd say 11 days but it would only get the worm the edge of the hole but not over it.

    Show me the answer then, smarty pants.

    The answer is 11 as you stated in your reasoning because if he is at the top of the hole, then there is no reason to slip backwards. I'm not a smarty pants - I just enjoy a good riddle honey!

    I disagree. 11 will get you to the top but NOT over the hole. The bloody worm needs to have additional height to get over the hump, so to speak. 11 gets you to the rim but NOT over. Sorry, pal.

    changmai, although your reasoning is good your answer is only closer to the right answer(s) than whitchway's which (pun completely incidental)is farthest.

    doolittle enjoys this chatter about worms...however, this worm would be very ill. most worms would make it out in 7-40 minutes, depending on whether they napped.

    Soo doo I except this is not a chatter about worms.

    The move is going...despite my pain! So Doo Do Well? & how r u val?

     


    There are different answers for different size/length  worms.


    It would take a one inch long worm 12 days to be out of the hole.


    A two inch long worm will be half out of the hole at the end of 12th day. It would take this worm another 3rd of the 13th day to be completely out.


    A three inch long worm will have his 1st 3rd out of the hole at the end of 12th day. Assuming it can hold on into this position it would take this worm 2/3 of the 13th day to be out of the hole.


    And so on...

    I took the worm out to use as fishing bait..............................

    very cruel :( How long did it take to get the fish out ow water?
