Question

16 Задание 16 Велосипедист и пешеход одновременно начали движение из пункта А в пункт В. Когда велосипедист приехал в пункт В, пешеходу осталось пройти две трети всего пути. Когда пешеход пришёл в пункт В, велосипедист уже ждал его там 20 минут. Сколько минут ехал велосипедист из пункта А в пункт В? Запишите решение и ответ ше

Answer 1

Ответ:

10 минут

Объяснение:

20 минут - это две трети

Соответственно, три трети - 30 минут

Так как велосипедист ждал его там 20 минут, значит 30-20=10 минут ехал велосипедист

Ответ: 10 минут

Вроде бы так (Наверное, всё равно лучше самому проверить)

Answer 2

Task 16 Solution:

To solve this problem, we can use the information provided in the question and apply the principles of distance, time, and speed. Let's break down the solution step by step.

1. Let's assume the total distance from point A to point B is represented by d. 2. We'll use the concept of relative speed to find the time taken by the cyclist and the pedestrian to reach point B.

First, let's calculate the time taken by the pedestrian to reach point B.

The pedestrian covered the remaining 2/3 of the distance when the cyclist arrived at point B. This means the cyclist covered 1/3 of the distance while the pedestrian covered 2/3 of the distance.

Now, let's calculate the time taken by the pedestrian to cover 2/3 of the distance using the information provided in the search results.

The time taken by the pedestrian to cover 2/3 of the distance is given by the equation: \[ t = \frac{d}{s} \] where: - \( t \) = time taken - \( d \) = distance - \( s \) = speed

Using the information from the search results, we can calculate the time taken by the pedestrian.

\[ t = \frac{2d}{3s} \]

Next, let's calculate the time taken by the cyclist to cover the entire distance.

When the pedestrian arrived at point B, the cyclist had been waiting for 20 minutes. This waiting time can be converted to hours for consistency in units.

Now, let's calculate the time taken by the cyclist to cover the entire distance using the information provided in the search results.

The time taken by the cyclist to cover the entire distance is given by the equation: \[ t = \frac{d}{s} \] where: - \( t \) = time taken - \( d \) = distance - \( s \) = speed

Using the information from the search results, we can calculate the time taken by the cyclist.

\[ t = \frac{d}{s} \]

By solving these equations, we can find the time taken by the cyclist to cover the distance from point A to point B.

Let's proceed with the calculations.
