A turtle is at the bottom of a 13 foot well. Each day it crawls up 5 feet, but each night it slips back 3 feet. After how many days will the turtle reach the top of the well?

Answer 1

11
9
7
5

It will take it 5 days to reach the top.

Answer 2

two feet every 2 days until we get within five

2*4 = 8 in 8 days
now the ninth day we go up to 8+5 = 13 so we are free after 9 days

Answer 3

whoops sorry, forgot that he works at night.

2 * 4 = 8
then out the next day, 5 days
