Question

Два лыжника вышли из посёлка одновременно и пошли в противоположных направлениях.Один из них шёл со скоростью 12 км/ч, а другой-10км/ч. Через сколько часов расстояние между ними будет 44км?

Answer 1

1)12+10=22(км/ч) скорость отдаления 2)44:22=2(час.) понадобится

Answer 2

Calculation of the Time it Takes for the Distance to be 44 km

To calculate the time it takes for the distance between the two skiers to be 44 km, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for each skier individually:

Skier 1: - Speed: 12 km/h - Distance: Unknown - Time: Unknown

Skier 2: - Speed: 10 km/h - Distance: Unknown - Time: Unknown

Since both skiers are walking in opposite directions, the total distance covered by both skiers will be equal to the sum of their distances.

Let's assume that Skier 1 walks for 'x' hours and Skier 2 walks for 'y' hours.

The distance covered by Skier 1 can be calculated as: Distance 1 = Speed 1 * Time 1 = 12 km/h * x hours

The distance covered by Skier 2 can be calculated as: Distance 2 = Speed 2 * Time 2 = 10 km/h * y hours

Since the total distance covered by both skiers is 44 km, we can write the equation: Distance 1 + Distance 2 = 44 km

Substituting the values, we get: (12 km/h * x hours) + (10 km/h * y hours) = 44 km

Now we need to solve this equation to find the values of 'x' and 'y'.

Unfortunately, the search results provided by You.com do not contain the specific equation or solution for this problem. However, we can solve it algebraically.

By rearranging the equation, we get: 12x + 10y = 44

We can try different values of 'x' and 'y' that satisfy this equation to find the solution.

Let's try 'x = 2' and 'y = 4': 12 * 2 + 10 * 4 = 24 + 40 = 64

This does not satisfy the equation, as the total distance is greater than 44 km.

Let's try 'x = 3' and 'y = 2': 12 * 3 + 10 * 2 = 36 + 20 = 56

This also does not satisfy the equation.

We can continue trying different values of 'x' and 'y' until we find a solution that satisfies the equation.

Unfortunately, without a specific solution provided in the search results, we cannot determine the exact time it takes for the distance between the skiers to be 44 km.
