Question

По вертикальному столбу высотой 6м ползёт улитка. За день она поднимается на 4м, а за ночь опускается на 3м. Через сколько дней улитка доберётся до вершины столба?

Answer 1

I день - 1 м
II день - 1+4-3=2 м
III день - 2+4=6 м

 

Улитка стартует с нулевой отметки, за день она поднимается на 4 м, а за ночь опускается на 3 м, таким образом на 2 м улитка заберётся за 2 суток. С утра следующего дня улитка стартует с высоты 2 м, следовательно к вечеру она достигнет вершины столба.

 

Ответ: 2,5 дня.

Answer 2

Problem Analysis

We are given that a snail is crawling up a vertical pole that is 6 meters tall. During the day, the snail climbs up 4 meters, and during the night, it slides down 3 meters. We need to determine how many days it will take for the snail to reach the top of the pole.

Solution

To solve this problem, we can calculate the net distance the snail covers each day. The net distance is the difference between the distance climbed during the day and the distance slid down during the night.

Let's calculate the net distance covered by the snail each day:

- During the day, the snail climbs up 4 meters. - During the night, the snail slides down 3 meters.

Therefore, the net distance covered by the snail each day is 4 meters - 3 meters = 1 meter.

Since the snail needs to climb a total of 6 meters to reach the top of the pole, we can divide the total distance by the net distance covered each day to find the number of days it will take:

6 meters / 1 meter = 6 days.

Therefore, it will take the snail 6 days to reach the top of the pole.

Answer

The snail will reach the top of the pole in 6 days.
