A Jumping Frog!

A frog starts climbing a 30 ft wall. Each hour he climbs 3 ft and slips back 2 ft. How many days does it take him to reach the top and get out?

    It'll take one day and three hours (27 hours) for the frog to get out.
    In 27 hours, it would've covered 27 feet. In the next hour, it'll jump 3 feet and get out.

    At the end of 27 hours he is 3 ft from the top. And during the 28th hour he climbs the remaining 3ft and he is out So answer is 28 hours.
