Question

Улитка за день поднимается на 4 метра а за ночь опускается на 2 метра. За сколько дней она поднимится на вершину столба высотой 8 метров? С решением сделайте пожалуйста

Answer 1

В первый день + ночь она прошла 4-2 = 2м
второй день 2+4 - 2=4 м
третий день 4 + 4-2 = 6 м
четвертый день 6 м +4 -2 = 8м 
возможно вам нужно использовать деление, то 8/2=4 (где 2 это прохождение за сутки)
возможно нужно учитывать только дни, тогда хватает 3,5 дня ( т.е. 3 суток и половину четвертого дня)
Вы уже смотрите как вы решаете в школе

Answer 2

4:2=2 метра в день; 8:2=4 дня

Answer 3

Problem Analysis

We are given that a snail climbs 4 meters during the day and descends 2 meters during the night. We need to determine how many days it will take for the snail to reach the top of an 8-meter 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 descended during the night.

Let's assume it takes "x" days for the snail to reach the top of the pole. During these "x" days, the snail will climb a total of 4x meters and descend a total of 2x meters.

The net distance covered by the snail each day is given by the equation: Net distance = Distance climbed during the day - Distance descended during the night

Since the snail needs to reach a height of 8 meters, the net distance covered each day should be equal to or greater than 8 meters.

Setting up the equation: 4x - 2x >= 8

Simplifying the equation: 2x >= 8

Dividing both sides of the equation by 2: x >= 4

Therefore, the snail will take at least 4 days to reach the top of the 8-meter pole.

Answer

The snail will take at least 4 days to reach the top of the 8-meter pole.

Explanation

During the first day, the snail climbs 4 meters. At the end of the day, it is at a height of 4 meters. During the second day, the snail climbs another 4 meters. At the end of the day, it is at a height of 8 meters, reaching the top of the pole.

Therefore, it takes a minimum of 4 days for the snail to reach the top of the 8-meter pole.
