A snail is crawling along a vertical pillar 6 meters high. During the day it rises by 4 meters

A snail is crawling along a vertical pillar 6 meters high. During the day it rises by 4 meters and during the night it drops by 3 meters. How many days will it take for the snail to reach the top of the pillar?

This task is solved in two steps. First, we find out what path the snail goes through during the day and during the night. Since in the problem statement it is said that the snail rises by 4 meters during the day, and descends by 3 meters during the night. Let’s do the subtraction. The next step is to find out in how many days the snail will reach the top of the 6 meter high pillar. Let’s do the division.

1) 4-3 = 1 (m) – the snail rises during the day and during the night;
2) 6/1 = 6 (days) – the snail will reach the top of the pillar.

Answer: after 6 days, the snail will reach the top of the pillar.
