Question

Два лыжника вышли одновременно из одного пункта в противоположных направлениях. Скорость одного лыжника 15 км/ч, а другого 10 км/ч. На сколько километров они удалятся друг от друга за один час? за 2 часа? за 3 часа? заранее спасибо))))))))))

Answer 1

1)15км/ч+10км/ч=25 км/ч скорость отдаления
2)25км/чх2=на50км отдалятся лыжники за 2 часа
3)25км/чх3=на75 км отдалятся лыжники за 3 часа
Ответ:50км,75км.

Answer 2

1)15+10=25(км/ч)- скорость удаления.
2)25*1=25км-удалятся друг от друга за 1 час.
3)25*2=50(км)- за 2часа.
4)25*3=75(км)- удалятся за 3часа.

Answer 3

Calculation of Distance between Skiers

To calculate the distance between the two skiers, we need to determine how far each skier travels in a given time period.

Let's calculate the distances for each time period:

For one hour:

Skier 1 travels at a speed of 15 km/h, so in one hour, they will travel 15 kilometers.

Skier 2 travels at a speed of 10 km/h, so in one hour, they will travel 10 kilometers.

Therefore, the distance between the two skiers after one hour is the sum of their individual distances: 15 km + 10 km = 25 km.

For two hours:

Using the same logic, we can calculate the distances for two hours:

Skier 1: 15 km/h * 2 hours = 30 kilometers.

Skier 2: 10 km/h * 2 hours = 20 kilometers.

The distance between the two skiers after two hours is the sum of their individual distances: 30 km + 20 km = 50 km.

For three hours:

Again, using the same logic, we can calculate the distances for three hours:

Skier 1: 15 km/h * 3 hours = 45 kilometers.

Skier 2: 10 km/h * 3 hours = 30 kilometers.

The distance between the two skiers after three hours is the sum of their individual distances: 45 km + 30 km = 75 km.

Therefore, the distances between the two skiers after one hour, two hours, and three hours are 25 km, 50 km, and 75 km, respectively.
