Question

велосипедист зп два часа проехал путь от пункта А до пункта В в первый час он проехал три седьмых пути а во второй час оставшиеся 16 км найдите расстояние в киллометрах между панктами А и В

Answer 1

1. 7/7 - 3/7 = 4/7 — путь, который велосипедист проехал за второй час
2. 16 : 4 = 4 км — это 1/7 пути
3. 3*4 = 12км — путь, который проехал велосипедист за первый час
4. 12 + 16 = 28км — расстояние от пункта А до пункта В.

Answer 2

Problem Analysis

A cyclist traveled from point A to point B in two hours. In the first hour, the cyclist covered three-sevenths of the distance, and in the second hour, the remaining 16 km. We need to find the distance between points A and B in kilometers.

Solution

Let's assume the total distance between points A and B is D km.

According to the problem, in the first hour, the cyclist covered three-sevenths of the distance, which is (3/7)D km.

In the second hour, the cyclist covered the remaining distance, which is D - (3/7)D = (4/7)D km.

We are given that the distance covered in the second hour is 16 km. So, we can set up the following equation:

(4/7)D = 16

To find D, we can solve this equation.

Calculation

Let's solve the equation to find the value of D:

(4/7)D = 16

Multiplying both sides by 7/4:

D = (16 * 7) / 4

D = 28 km

Answer

The distance between points A and B is 28 kilometers.
