Lovelorn Snail (Posted on 2003-11-27) Difficulty: 2 of 5
On Valentine's Day in 1996, there was a snail (his name is Herb) at the bottom of an empty well that is 30 feet tall. The well had run dry, but it had slippery, moss covered walls. So, during the day (he woke up at 6am), Herb was able to climb 3 feet up, but while he slept at night (he went to sleep at 10pm), he slipped back down 2 feet.

On what date did Herb get out of the well?

if he was only able to climb 3 feet per day he would actually have needed an extra day to get out of the well. March 12 only takes him to the top of the well at 30 feet. in order for him to be out he would have to go further than 30 feet if only by an inch. still another day would have been required.
