Question

Скорость одного пешехода 3 км\ч, другого- 4 км\ч. расстояние между сёлами 25 км. На каком расстоянии друг от друга окажутся пешеходы через 3ч  

Answer 1

Calculation of the Distance between Pedestrians

To calculate the distance between the two pedestrians after 3 hours, we need to determine the distance each pedestrian has traveled in that time.

Given: - Speed of the first pedestrian: 3 km/h - Speed of the second pedestrian: 4 km/h - Distance between the villages: 25 km

To find the distance traveled by each pedestrian, we can use the formula:

Distance = Speed × Time

For the first pedestrian: Distance1 = 3 km/h × 3 h = 9 km

For the second pedestrian: Distance2 = 4 km/h × 3 h = 12 km

Now, let's calculate the distance between the two pedestrians after 3 hours:

Total distance between the pedestrians = Distance2 - Distance1 Total distance = 12 km - 9 km = 3 km

Therefore, the two pedestrians will be 3 km apart after 3 hours.

Please note that the above calculation assumes that the pedestrians are walking in the same direction. If they are walking towards each other, the calculation would be different.
