A snail is moving along a vertical pillar 6 meters high. During the night, it rises by 4 meters, in the day it drops by 3 meters. At what height will the snail be in a day if it starts to rise in the evening?

Since the snail begins its movement at night, during this period it will rise 4 meters, after which it will descend a meter back.
In this case, in a day (from the beginning of the night to the beginning of the night of the next day), she will overcome:
4 – 3 = 1 meter.
From this we can conclude that in 2 full days the snail will rise to a height equal to:
1 * 2 = 2 meters.
In order to climb to the top of the pillar, she will need to continue her movement for one more night.
We get:
2 + 4 = 6 meters.
Answer:
In a day – 1 meter.
Will be at the top in 3 nights and 2 days.
