The Snail on the Wall
If this happens every day, how many days will the snail take to reach the top of a wall 34 ft in height?
14
Solution:
On the first day, the snail climbs up 8 ft and slips down 6 ft while sleeping. So, next morning, it is 2 ft from where it started. The snail thus travels 2 ft upwards every day. Therefore, in 13 days, it has traveled a distance of 26 ft from the bottom.
Here lies the catch to the problem! On the last day, the snail travels 8 ft upwards and hence reaches the top of the wall in a total of 14 days.
Alternative Solution through Equation:
Let x be the number of days the snail takes to reach the top of the wall 34 ft in height.
On the last day, the snail will reach the top by traveling 8 ft upwards and there will not be any question of slipping down.
The number of remaining days excluding the last day are (x − 1). Since the snail climbs up 8 ft and slips down 6 ft while sleeping, it travels 2 ft upwards on each of these remaining days. Thus,
Distance traveled on last day + Distance traveled on remaining days = Wall height; or
8 + 2 (x − 1) = 34
On solving the above equation, we get
2 (x − 1) = 34 − 8 = 26; or
x = (26 / 2) + 1 = 14.
