Question

Расстояние между александровкой и Бекасово 4 км 500 м.из александровки в Бекасово вышел пешеход со скоростью 60 м /мин. Через 5 минут после его выхода навстречу вышел второй пешеход со скоростью 80 м/мин. Через сколько времени после выхода второго пешехода и на каком расстоянии от Бекасово произошла встреча?

Calculation of Meeting Time and Distance

To calculate the time and distance at which the two pedestrians meet, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for each pedestrian to reach the meeting point.

The first pedestrian walks at a speed of 60 m/min. Since the distance between Alexandrovka and Bekasovo is 4 km 500 m (or 4,500 m), we can calculate the time it takes for the first pedestrian to reach the meeting point:

Time taken by the first pedestrian = Distance / Speed = 4,500 m / 60 m/min = 75 min

After 5 minutes, the second pedestrian starts walking towards the first pedestrian. The second pedestrian walks at a speed of 80 m/min. Therefore, the time taken by the second pedestrian to reach the meeting point is:

Time taken by the second pedestrian = Distance / Speed = 4,500 m / 80 m/min = 56.25 min

To find out when the second pedestrian reaches the meeting point, we need to add the time taken by the first pedestrian (75 min) and the time taken by the second pedestrian (56.25 min) to the initial 5 minutes:

Total time = Time taken by the first pedestrian + Time taken by the second pedestrian + Initial 5 minutes = 75 min + 56.25 min + 5 min = 136.25 min

Therefore, the two pedestrians will meet approximately 136.25 minutes after the second pedestrian starts walking.

Now, let's calculate the distance from Bekasovo at which the meeting occurs.

The first pedestrian walks for 75 minutes before the second pedestrian starts walking. During this time, the first pedestrian covers a distance of:

Distance covered by the first pedestrian = Speed * Time = 60 m/min * 75 min = 4,500 m

Since the total distance between Alexandrovka and Bekasovo is 4,500 m, the meeting point will be at the remaining distance from Bekasovo:

Distance from Bekasovo = Total distance - Distance covered by the first pedestrian = 4,500 m - 4,500 m = 0 m

Therefore, the meeting point is at a distance of 0 meters from Bekasovo.

To summarize: - The two pedestrians will meet approximately 136.25 minutes after the second pedestrian starts walking. - The meeting point is at a distance of 0 meters from Bekasovo.

Please note that the search results did not provide specific information about the distance between Alexandrovka and Bekasovo or the walking speeds of the pedestrians. Therefore, the calculations provided are based on the information provided in the user's question.
