Question

Два лыжника вышли из посёлка одновременно в противоположных направлениях один из них шёл со скоростью 12 км/ч а другой 10 км/ч через сколько часов расстояние между ними будет 44 км ? какое расстояние пройдёт за это время каждый лыжник

Answer 1

1)12+10=22(км/ч)
2)44:22=2(ч)
3)12*2=24(км) -прошёл первый
4)10*2=20(км) -прошёл второй

Answer 2

1)12+10 =22(км/ч) скорость сближения.
2)44:22 через 2 час расстояние междку ними будет 44 км.
3)12××=24км пройдет первфй лыжник.
4) 10×2= 20км пройднт за 2 часа второй лыжник.

Answer 3

Problem Analysis

Two skiers start from a village simultaneously in opposite directions. One skier has a speed of 12 km/h, while the other has a speed of 10 km/h. We need to determine how many hours it will take for the distance between them to be 44 km, as well as the distance each skier will have traveled during that time.

Solution

Let's assume the time it takes for the skiers to meet is t hours. During this time, the skier with a speed of 12 km/h will have traveled a distance of 12t km, and the skier with a speed of 10 km/h will have traveled a distance of 10t km.

Since they are moving in opposite directions, the sum of their distances should be equal to the total distance between them, which is 44 km. Therefore, we can write the equation:

12t + 10t = 44

Simplifying the equation:

22t = 44

Dividing both sides by 22:

t = 2

So, it will take 2 hours for the skiers to meet.

To find the distance each skier will have traveled during this time, we can substitute the value of t into the distance formulas:

Distance traveled by the skier with a speed of 12 km/h: 12 * 2 = 24 km

Distance traveled by the skier with a speed of 10 km/h: 10 * 2 = 20 km

Therefore, the skier with a speed of 12 km/h will have traveled 24 km, and the skier with a speed of 10 km/h will have traveled 20 km during the 2 hours it takes for them to meet.

Answer

It will take 2 hours for the skiers to be 44 km apart. During this time, the skier with a speed of 12 km/h will have traveled 24 km, and the skier with a speed of 10 km/h will have traveled 20 km.
