Question

з двох сіл одночасно назустріч один одному вирушили два пішоходи,швидкість першого пішохода дорівнює 5 км /год ,що становить 5/6 швидкості другого.через скільки годин після початку руху вони зустрінуться, якщо відстань між селами дорівнює 22 км?

Answer 1

5:5/6=6 км/ч скорость второго пешехода

5+6=11 км/ч   общая скорость пешеходов

22:11=2 ч

Через 2ч пешеходы встретятся

Answer 2

1)5:5*6=6км/ч-скорость второго.

2)5+6=11км/ч-скорость сближения.

3)22:11=через 2 часа-они встретятся.

Answer 3

Problem Analysis

We have two pedestrians moving towards each other from two different villages. The speed of the first pedestrian is 5 km/h, which is 5/6 of the speed of the second pedestrian. We need to determine how many hours it will take for them to meet if the distance between the villages is 22 km.

Solution

Let's assume the speed of the second pedestrian is x km/h. According to the problem statement, the speed of the first pedestrian is 5 km/h, which is 5/6 of the speed of the second pedestrian. Therefore, we can write the equation:

5 = (5/6)x

To find the value of x, we can multiply both sides of the equation by 6:

30 = 5x

Dividing both sides of the equation by 5, we get:

x = 6

So, the speed of the second pedestrian is 6 km/h.

Now, we can calculate the time it will take for them to meet. We can use the formula:

time = distance / speed

The distance between the villages is given as 22 km. Let's calculate the time it will take for them to meet:

time = 22 km / (5 km/h + 6 km/h)

Simplifying the expression, we get:

time = 22 km / 11 km/h

Finally, we can calculate the time:

time = 2 hours

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

Answer

It will take 2 hours for the two pedestrians to meet.
