Question

Из сел, находящихся на расстоянии 50 км друг от друга, вышли на встречу друг другу два пешехода. Один шел со скоростью 6 км/ч, другой — со скоростью 4 км/ч. Через какое время они встретятся? А) (6 + 4) • 50 Б)50:6 + 50:4 В) 50: (6 + 4) Г) 50: (6-4) помогите пожалуйста там надо выбрать ответ А Б В Г

Answer 1

ответ в

потому что мы должны узнать время

6+4 это общая скорость

50:(6+4) мы узнаем время

Answer 2

Ответ:В
Пошаговое объяснение :Чтобы найти время нужно расстояние разделить на скорость

Answer 3

Problem Analysis

Two pedestrians are walking towards each other from two different villages that are 50 km apart. One pedestrian is walking at a speed of 6 km/h, while the other is walking at a speed of 4 km/h. We need to determine how long it will take for them to meet.

Solution

To find the time it takes for the pedestrians to meet, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for each pedestrian to cover the distance between the villages.

For the pedestrian walking at a speed of 6 km/h: Time1 = Distance / Speed1 = 50 km / 6 km/h

For the pedestrian walking at a speed of 4 km/h: Time2 = Distance / Speed2 = 50 km / 4 km/h

To find the total time it takes for them to meet, we can add the individual times together: Total Time = Time1 + Time2

Let's calculate the total time.

Calculation

Time1 = 50 km / 6 km/h = 8.33 hours

Time2 = 50 km / 4 km/h = 12.5 hours

Total Time = Time1 + Time2 = 8.33 hours + 12.5 hours = 20.83 hours

Therefore, it will take approximately 20.83 hours for the two pedestrians to meet.

The correct answer is В) 50: (6 + 4).
