Question

Два лыжника вышли из поселка едино временно и пошли в противопоказаны стороны. один из них шел со скоростью 12км/ч, а другой 10км/ч. через сколько часов расстояние между ними будет 44 км?

Answer 1

Расстояние 44 км будет через 2 часа

Answer 2

V1+V2=Vудал  12+10=22км/ч   t=S:V  44:22=2часа

Answer 3

Problem Analysis

Two skiers start from a village at the same time and head in opposite directions. One skier is traveling at a speed of 12 km/h, while the other is traveling at 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.

Solution

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's assume that the time it takes for the skiers to be 44 km apart is 't' hours.

The distance covered by the first skier in 't' hours is given by: Distance1 = Speed1 × t

The distance covered by the second skier in 't' hours is given by: Distance2 = Speed2 × t

Since they are moving in opposite directions, the total distance between them is the sum of the distances covered by each skier: Total Distance = Distance1 + Distance2

We can now set up the equation: Total Distance = Distance1 + Distance2 = 44 km

Substituting the values we have: (Speed1 × t) + (Speed2 × t) = 44 km

Now we can solve this equation to find the value of 't'.

Let's calculate the time it takes for the skiers to be 44 km apart.

Calculation

Using the given speeds: - Speed1 = 12 km/h - Speed2 = 10 km/h

Substituting these values into the equation: (12 km/h × t) + (10 km/h × t) = 44 km

Simplifying the equation: 22t = 44

Dividing both sides by 22: t = 2

Therefore, it will take 2 hours for the distance between the skiers to be 44 km.

Answer

The distance between the two skiers will be 44 km after 2 hours.
