The snail crawls up the 10m high pillar. During the day it rises by 5m, and during the night it drops by 4m.

The snail crawls up the 10m high pillar. During the day it rises by 5m, and during the night it drops by 4m. How long does it take for a snail to get from the foot to the top of the pillar?

Given:
The height of the post is 10 meters.
The path per day is 5 meters.
The path is 4 meters at night.

Let’s calculate what distance the snail travels in a day, if we take into account its movement down at night:
5 – 4 = 1 meter.
That is, the snail travels 1 meter to the target per day.
Let’s calculate how many days it will take for her to complete the entire pillar:
10: 1 = 10 days.
Answer: the snail will cover the required distance in 10 days.
