Два лыжника вышли одновременно навстречу друг другу из двух посёлков,расстояние между которыми 48 км.Скорость одного лыжника 11 км./ч,а другого-13 км./ч.Через сколько часов лыжники встретятся?

Answer 1

11+13=24 км расстояние, которое проходят оба лыжника за час
48:24=2 часа
Ответ: лыжники встретятся через 2 часа

Answer 2

48:(11+13)=2(ч)
Ответ: через 2 часа.

Answer 3

Problem Analysis

We have two skiers who start simultaneously from two different villages and are moving towards each other. The distance between the villages is 48 km. The speed of one skier is 11 km/h, and the speed of the other skier is 13 km/h. We need to determine how many hours it will take for the skiers to meet.

Solution

To find the time it takes for the skiers to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two skiers.

Let's calculate the time it takes for the skiers to meet.

Calculation

The distance between the villages is 48 km. The speed of the first skier is 11 km/h. The speed of the second skier is 13 km/h.

The relative speed of the skiers is 11 km/h + 13 km/h = 24 km/h.

Using the formula, we can calculate the time it takes for the skiers to meet:

Time = Distance / Relative Speed

Time = 48 km / 24 km/h = 2 hours.

Therefore, the skiers will meet after 2 hours.

Answer

The skiers will meet after 2 hours.
