Question

Винни-Пух и Пятачок вышли из своих домиков навстречу друг другу и встретились через 20 минут. После встречи они вместе пошли к дому Пуха со скоростью Пятачка. Через сколько минут после встречи они придут к дому Пуха, если скорость Винни-Пуха в два раза больше скорости Пятачка, когда они шли навстречу? Срочно помогите

Answer 1

Ответ:

V₁ - скорость Винни

V₂ - скорость Пятачка

V₁ = 2*V₂

V₁ + V₂ = 2*V₂+V₂ = 3*V₂

V₂ = S*t/3

Значит за 20 мин Винни Пух прошел 2/3 части пути, а Пятачок прошел 1/3 часть пути.

Значит до дома Винни Пуха им нужно пройти 2/3 пути. со скоростью Пятачка.20*2=40мин.

к дому Пуха придут через 40 мин.

Problem Analysis

In this problem, we are given that Winnie-the-Pooh and Piglet leave their houses to meet each other. They meet after 20 minutes and then go to Pooh's house at Piglet's speed. We need to determine how many minutes it will take for them to reach Pooh's house if Pooh's speed is twice that of Piglet's when they are walking towards each other.

Solution

Let's assume that Piglet's speed is x units per minute. Since Pooh's speed is twice that of Piglet's, Pooh's speed will be 2x units per minute.

When they are walking towards each other, their combined speed will be the sum of their individual speeds. Therefore, their combined speed will be x + 2x = 3x units per minute.

We know that they meet after 20 minutes. So, the distance between their houses can be calculated by multiplying their combined speed by the time it takes for them to meet. Therefore, the distance between their houses is 3x * 20 = 60x units.

After they meet, they go to Pooh's house at Piglet's speed. Since the distance between their houses is 60x units, it will take them 60x / x = 60 minutes to reach Pooh's house.

Therefore, it will take them 60 minutes to reach Pooh's house after they meet.

Answer

After they meet, it will take Winnie-the-Pooh and Piglet 60 minutes to reach Pooh's house.
