3. A snail sits at the bottom of a 30 feet wall. Each hour it can climb 3 feet, but it then slips 2 feet. How long does it take to reach the top.
A: 28 hours.
In each hour snail climbs feet and drops 2 feet.
So, net distance it climbs is 3-2= 1 foot. So, in 27 hours it climbs 27 feet.
In 28th hour it climbs another 3 feet and reaches top of the wall before falling.
