Question

равлик повзе по стовбуру дерева заввишки12метрів .Зф день він піднімається на 3 метри ,але за ніч сповзає вниз на 2 метри .Скільки днів потрібно равлику,щоб дістатися до верхівки?

Answer 1

3-2+3-2...

Это все равно что подниматься на 1м в день. Тоесть, он будет ползти 12 дней.

Answer 2

Problem Analysis

We have a snail climbing up a tree. The tree is 12 meters tall. During the day, the snail climbs up 3 meters, but at night it slides down 2 meters. We need to determine how many days it will take for the snail to reach the top of the tree.

Solution

To solve this problem, we can calculate the number of days it will take for the snail to reach the top of the tree by considering its daily progress and nightly regression.

Let's break down the problem step by step:

1. Calculate the net progress the snail makes each day by subtracting the distance it slides down at night from the distance it climbs up during the day. In this case, the net progress is 3 meters - 2 meters = 1 meter per day.

2. Divide the total height of the tree (12 meters) by the net progress the snail makes each day to find the number of days it will take for the snail to reach the top. In this case, it will take 12 meters / 1 meter per day = 12 days.

Therefore, it will take the snail 12 days to reach the top of the tree.

Conclusion

In conclusion, the snail will take 12 days to reach the top of the tree if it climbs up 3 meters during the day and slides down 2 meters at night.
