Question

Два пешехода вышли одновременно из двух деревень навстречу друг другу .один шёл со скоростью 5 км\ч,скорость второго 4 км\ч. Встретились через 3 часа Каково расстояние между деревнями?

Answer 1

5+4=9
9*3=27расстояние

Answer 2

За 3 часа первый пеш прошел расстояние 15км, 3часа*5км.ч=15км. Второй пеш прошел 12 км, 3*4=12км. Общее расстояние 15км+12км=27км. Ответ 27 км

Answer 3

Problem Analysis

Two pedestrians are walking towards each other from two different villages. One pedestrian is walking at a speed of 5 km/h, while the other is walking at a speed of 4 km/h. They meet after 3 hours. We need to find the distance between the villages.

Solution

To find the distance between the villages, we can use the formula:

Distance = Speed * Time

Let's calculate the distance traveled by each pedestrian and then find the total distance between the villages.

1. The first pedestrian is walking at a speed of 5 km/h. So, in 3 hours, the first pedestrian would have traveled a distance of: Distance1 = Speed1 * Time = 5 km/h * 3 h = 15 km.

2. The second pedestrian is walking at a speed of 4 km/h. So, in 3 hours, the second pedestrian would have traveled a distance of: Distance2 = Speed2 * Time = 4 km/h * 3 h = 12 km.

3. The total distance between the villages is the sum of the distances traveled by each pedestrian: Total Distance = Distance1 + Distance2 = 15 km + 12 km = 27 km.

Therefore, the distance between the villages is 27 kilometers.

Answer

The distance between the two villages is 27 kilometers.
