Question

От станции метро одновременно отошли в противоположных направлениях два автобуса.Скорость одного из них 60 км-ч ,а скорость другого 70км-ч.Каждый автобус был в пути 3 часа.Какое расстояние между автобусами?

Answer 1

узнаем расстояние, которе прошел каждый поезд:

1)60*3=180 км - прошел 1-ый поезд

2)70*3=210 км - прошел 2-ой поезд

узнаем расстояние, накотором они оказались, относительно друг друга:

3)180+210=390 км.

Answer 2

 1) 60+70 =130(км-ч)-скорость удаления.

 

 

 2)130*3=390(км)-между автобусами через 3 часа.

          Ответ:390 километров.

 

 

Answer 3

Problem Analysis

Two buses depart from a metro station in opposite directions. The speed of one bus is 60 km/h, and the speed of the other bus is 70 km/h. Both buses are in motion for 3 hours. We need to find the distance between the two buses.

Solution

To find the distance between the two buses, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by each bus and then find the difference between the two distances.

1. Distance traveled by the first bus: - Speed of the first bus = 60 km/h - Time traveled by the first bus = 3 hours - Distance = Speed x Time = 60 km/h x 3 hours = 180 km

2. Distance traveled by the second bus: - Speed of the second bus = 70 km/h - Time traveled by the second bus = 3 hours - Distance = Speed x Time = 70 km/h x 3 hours = 210 km

3. Difference between the distances: - Distance between the two buses = Distance of the second bus - Distance of the first bus = 210 km - 180 km = 30 km

Therefore, the distance between the two buses is 30 km.
