A snail is climbing to the top of a wall. It starts from the bottom of the wall and after climbing
37 of the height of the wall, it begins to rain. During the rain, the snail slips down 4 m. When the rain stops, the snail climbs up the remaining
67 of the height of the wall to reach the top of the wall. Find the height of the wall.
Fraction of the height of the wall that it climbed before the rain
= 1 -

27
Distance that the snail slipped = 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Height of the wall
= 7 u
= 7 x 2
= 14 m
Answer(s): 14 m
