Question

A snail is at the bottom of a 10 foot well. Every

day, he crawls up 3 feet, but at night, he slips
down 2 feet. How many days will it take for him to get
out of the well?

Answer 1

8 days

Explanation:

We get 8 days because the snail gets one foot higher every day. By the morning of the 8th day, the snail is 7 feet up and just needs to climb its daily 3 feet and it will be out of the well. You don't need 10 days because the snail only falls at night.

Answer 2

10 days.

Explanation:

3-2 = 1 foot of progress per day.
