A snail is at the bottom of a 30 foot well. Every hour the snail is able to climb up 3 feet, then immediately slide back down 2 feet. How many hours does it take for the snail to get out of the well?
Submitted by: Muhammad28 hours. The snail is travelling at one foot per hour, except on the 28th hour the snail has already reached the top of the well, so it will not slide down the 2 feet.
