Question

Высота сосны 20 метров.По ней ползёт улитка,каждый день поднимаясь на 2 метра вверх и каждую ночь опускаясь на 1 метр.за сколько дней улитка поднимется на вершину?

Answer 1

мне кажется за 20 дней так как если улитка подумается на 2 метра а опускается на 1 то за сутки 2-1=1 м. (подняла за д) , за 20 дней тогда=1 умножить 20=20 м.(за 20 дней)

Answer 2

Calculation of the Snail's Journey

To calculate the number of days it will take for the snail to reach the top of the pine tree, we need to consider its daily progress.

According to the given information, the snail climbs 2 meters during the day and descends 1 meter during the night. The height of the pine tree is 20 meters.

Let's break down the snail's journey:

- During the day, the snail climbs 2 meters. - During the night, the snail descends 1 meter.

To calculate the number of days it will take for the snail to reach the top, we can set up an equation:

Total number of days = (Total height of the tree - Distance climbed during the day) / (Distance climbed during the day - Distance descended during the night)

Plugging in the values:

Total number of days = (20 - 2) / (2 - 1)

Simplifying the equation:

Total number of days = 18 / 1

Therefore, the snail will take 18 days to reach the top of the pine tree.
