year 8 math

a snail is at the bottom of an empty trough with walls 40cm high. If the snail manages to move 4cm up a wall each day,
but slips 3cm each night, how long does it take the snail to reach the top of the trough?
it then continues over the wall and makes it's way down to the ground outside. how long does it take to get there?
