Question

Из двух посёлков , расстояние между которыми 57 км , вышли одновременно навстречу друг к другу два лыжника . Один шёл со скоростью 12км/ч, другой - 16 км/ч. Какой расстояние будет между лыжниками через 2 ч.

Answer 1

1) 12+16=28 скорость сближения
2)28*2=56 км прошли
3)57-56=1км
ОТВЕТ расстояние через 2 часа будет 1 км

Answer 2

1)12+16=28 (км/ч)скорость сближения лыжников.
2)28*2=56 (км) расстояние которое будет через 2 часа.
3)57-56=1 (км)
Ответ:1 км- расстояние, которое будет между лыжниками через 2 часа.

Problem Analysis

Two skiers start simultaneously from two villages that are 57 km apart. One skier has a speed of 12 km/h, while the other skier has a speed of 16 km/h. We need to find the distance between the skiers after 2 hours.

Solution

To find the distance between the skiers after 2 hours, we need to calculate the distance each skier has traveled in that time.

Let's start by calculating the distance traveled by the first skier. The formula to calculate distance is:

Distance = Speed × Time

For the first skier: - Speed = 12 km/h - Time = 2 hours

Substituting the values into the formula, we get:

Distance of the first skier = 12 km/h × 2 hours = 24 km

Now let's calculate the distance traveled by the second skier. Using the same formula:

For the second skier: - Speed = 16 km/h - Time = 2 hours

Substituting the values into the formula, we get:

Distance of the second skier = 16 km/h × 2 hours = 32 km

Now that we have the distances traveled by each skier, we can find the distance between them. Since they are moving towards each other, we can simply add their distances:

Total distance between the skiers = Distance of the first skier + Distance of the second skier = 24 km + 32 km = 56 km

Therefore, the distance between the skiers after 2 hours will be 56 km.

Answer

The distance between the two skiers after 2 hours will be 56 km.
