A worm is at the bottom of a forty foot hole. It can crawl upwards at the rate of four feet in one day, but at night, it slips back three feet. At this rate, how long will it take the worm to crawl out of the hole? explain

Salamo 3alaikom,

Since the worm crawls up 4 feets and then slips back 3 feet then its actual rate is 1 foot / day. So to get out of the hole it will take 40 days to come out.
