Question

Два пешехода вышли одновременно навстречу друг другу из двух деревень. первый может пройти расстояние между двумя деревнями за 8 часов, а второй за 6 часов. на какую часть растояния они приблизятся за 1 ч?

Answer 1

Примем за 1  все  расстояние

1:8=1/ 8  скорость 1 пешехода

1:6=1/6  скорость 2 пешехода 

1/8+1/6=3/24+4/24=7/24 приблизятся пешеходы за 1 час

Answer 2

Problem Analysis

Two pedestrians start walking towards each other from two different villages. The first pedestrian can cover the distance between the villages in 8 hours, while the second pedestrian can cover the same distance in 6 hours. We need to determine how much of the distance they will have covered in 1 hour.

Solution

To find out how much of the distance the pedestrians will have covered in 1 hour, we need to calculate their respective speeds. We can then use the formula `distance = speed * time` to find the distance covered by each pedestrian in 1 hour.

Let's calculate the speeds of the pedestrians first.

The first pedestrian can cover the distance between the villages in 8 hours, so their speed is `distance / time = 1 / 8` of the total distance per hour.

The second pedestrian can cover the same distance in 6 hours, so their speed is `distance / time = 1 / 6` of the total distance per hour.

Now, let's calculate the distance covered by each pedestrian in 1 hour.

The first pedestrian will cover `1 / 8` of the total distance in 1 hour.

The second pedestrian will cover `1 / 6` of the total distance in 1 hour.

Therefore, the two pedestrians will have covered a combined distance of `1 / 8 + 1 / 6` in 1 hour.

To simplify the calculation, we can find a common denominator for the fractions `1 / 8` and `1 / 6`, which is 24.

Converting the fractions to have a denominator of 24, we get `3 / 24` and `4 / 24`.

Adding these fractions together, we get `(3 + 4) / 24 = 7 / 24`.

Therefore, the two pedestrians will have covered 7/24 of the total distance in 1 hour.

Answer

The two pedestrians will have covered 7/24 of the total distance between the villages in 1 hour.
