Question

Из двух сел одновременно навстечу друг другу вышли два пешехода. Скорость одного пешехода равно 5 км/ч, что составляет пять шестых скорости второго. Через сколько часов после начала движения они встретятся, если растояние между селами равно 22 км?

Answer 1

Найдём скорость второго пешехода (нахождение числа по значению его дроби)
5 : 5/6  = 5×6/5 = 6 (км/ч )- скорость второго пешехода
5 + 6 = 11 (км/ч)  скорость их сближения
22 : 11 = 2 (ч)  Ответ: Через 2 часа пешеходы встретятся

Answer 2

Problem Analysis

We have two pedestrians who start walking towards each other from two different villages. The speed of one pedestrian is 5 km/h, which is five-sixths the speed of the second pedestrian. The distance between the villages is 22 km. We need to determine how many hours it will take for them to meet.

Solution

Let's assume the speed of the second pedestrian is x km/h. According to the problem, the speed of the first pedestrian is five-sixths of the speed of the second pedestrian. Therefore, we can write the equation:

5/6 * x = 5 km/h

To find the value of x, we can solve this equation:

x = (6/5) * 5 km/h = 6 km/h

Now that we know the speed of both pedestrians, we can calculate the time it will take for them to meet. We can use the formula:

time = distance / speed

Substituting the values, we get:

time = 22 km / (5 km/h + 6 km/h) = 22 km / 11 km/h = 2 hours

Therefore, it will take 2 hours for the pedestrians to meet.

Answer

The pedestrians will meet after 2 hours of walking.
