Question

Расстояние между Александровкой и Бекасово 4км 500м.Из Александровки в Бекасово вышел пешеход со скоростью 60м/мин через 5 мин после его выхода навстречу ему из Бекасово в Александровку вышел второй пешеход со скоростью 8 м/мин.Через сколько времени после выхода второго пешехода и на каком расстоянии от Бекасово произошла встреча?РеШиТе ПлИзззззз!!!!

Answer 1

Я предполагаю что скорость второго = 80 м/мин

1) 60*5=300 (м) прошел за 5 минут пешеход из Александровки
2) 4500-300=4200 (м) осталось пройти пешеходам вместе
3) 60+80=140 (м/мин) общая скорость пешеходов
4) 4200/140=30(мин) произошла встреча
5) 80*30=2400 (м) прошел второй пешеход от Бекасова до места встречи.

Ответ: через 30 минут, 2 км 400 метров

Answer 2

Calculation of Meeting Time and Distance

To solve this problem, we need to calculate the time it takes for the two pedestrians to meet and the distance from Bekasovo where the meeting occurs.

Given: - Distance between Alexandrovka and Bekasovo: 4 km 500 m - Speed of the first pedestrian (walking from Alexandrovka to Bekasovo): 60 m/min - Speed of the second pedestrian (walking from Bekasovo to Alexandrovka): 8 m/min

Let's calculate the time it takes for the two pedestrians to meet and the distance from Bekasovo where the meeting occurs.

Calculation:

1. Convert the distance between Alexandrovka and Bekasovo to meters: - 4 km 500 m = 4,500 m

2. Let's assume the time it takes for the second pedestrian to meet the first pedestrian is 't' minutes.

3. The distance covered by the first pedestrian in 't' minutes is: - Distance = Speed * Time - Distance = 60 m/min * t min = 60t meters

4. The distance covered by the second pedestrian in 't' minutes is: - Distance = Speed * Time - Distance = 8 m/min * t min = 8t meters

5. The total distance covered by both pedestrians when they meet is equal to the distance between Alexandrovka and Bekasovo: - 60t + 8t = 4,500 - 68t = 4,500 - t = 4,500 / 68 - t ≈ 66.18 minutes

6. The distance from Bekasovo where the meeting occurs is equal to the distance covered by the second pedestrian in 't' minutes: - Distance = 8t ≈ 8 * 66.18 ≈ 529.44 meters

Answer:

The two pedestrians will meet approximately 66.18 minutes after the second pedestrian starts walking. The meeting will occur at a distance of approximately 529.44 meters from Bekasovo.

Please note that these calculations are approximate and may vary slightly depending on the exact values used.
