Question

the wall is 20ft deep, the snail goes up 4ft every day and drops 2 ft every night. how many days does it take the snail to reach 20ft?

Answer 1

It takes the snail 10 days to reach 20 ft because if it loses 2 ft of the 4ft it climbs every day you can just calculate 20/2 and get 10 instead of 20/(4-2)

Answer 2

the snail will actually take 9days to reach the wall

hopefully this helped you

have a amazing nite or day
