Question

Улитка рауль находится на расстоянии 10 м от улитки Ули.Уля убегает от Рауля и каждый день проползает по 2 м. А Рауль хочет догнать Улю и за каждый день проползает 4 м. В какой день Рауль догонит Улю?

Answer 1

4-2=2 (Скорость с которой догоняет Рауль)
10/2=5 (Дней потребуется чтобы догнать)
Ответ: 5 дней

Answer 2

Problem Analysis

We are given that a snail named Raul is initially 10 meters away from another snail named Ula. Each day, Ula moves 2 meters away from Raul, while Raul moves 4 meters closer to Ula. We need to determine on which day Raul will catch up to Ula.

Solution

To solve this problem, we can set up an equation to represent the distance between Raul and Ula each day. Let's assume that the number of days is represented by d.

On the first day, the distance between Raul and Ula is 10 meters. Each day, Ula moves 2 meters away from Raul, so the distance between them increases by 2 meters. On the other hand, Raul moves 4 meters closer to Ula, so the distance between them decreases by 4 meters.

Therefore, the equation to represent the distance between Raul and Ula on each day is:

Distance = 10 + 2d - 4d

We want to find the day when Raul catches up to Ula, which means the distance between them becomes 0. So we can set up the equation:

10 + 2d - 4d = 0

Simplifying the equation, we get:

10 - 2d = 0

Solving for d, we find:

d = 5

Therefore, Raul will catch up to Ula on the 5th day
