Question

"A snail is at the bottom of a 30-foot well. Each day he climbs up three feet, but at night he slips back two feet. How many days will it take him to climb out of the well?"

Answer 1

On the first day, snail went up 3 feet and comes down two feet that bring him to 1 foot.

Next, it will reach 4 feet and will come down to 2 feet.

The third day, it will reach 5 feet and will slip to 3 feet.

Then the next day it will go to 6 and come to 4 feet.

This will take place in a total of 28 days if assumed that it won’t slip after reaching the top.
