Question

Помоги решить задачу .За 1 час лыжник прошёл 5/14 всего пути ,за второй час 7/14 всего пути, известно что за эти 2 часа лыжник прошёл 36 км .Сколько километров составляет весь путь лыжника?​

Answer 1

Ответ:

72

Пошаговое объяснение:

7/14 это половина пути известно что за 2 часа он прошел 36км значит 7/14 равно 36км 14/14= 36+36=72км

Answer 2

Problem Analysis

We are given that a skier covered 5/14 of the total distance in the first hour and 7/14 of the total distance in the second hour. We also know that the skier covered a total distance of 36 km in these two hours. We need to find the total distance covered by the skier.

Solution

Let's assume the total distance covered by the skier is D km.

According to the given information, the skier covered 5/14 of the total distance in the first hour and 7/14 of the total distance in the second hour. Therefore, the distance covered in the first hour is (5/14)D km and the distance covered in the second hour is (7/14)D km.

The total distance covered in these two hours is given as 36 km. So, we can write the equation:

(5/14)D + (7/14)D = 36

Simplifying the equation, we get:

(12/14)D = 36

Now, let's solve for D to find the total distance covered by the skier.

(12/14)D = 36

Multiplying both sides of the equation by (14/12), we get:

D = (36 * 14) / 12

Simplifying further, we find:

D = 42 km

Therefore, the total distance covered by the skier is 42 km.

Answer

The total distance covered by the skier is 42 km.
