Question

Первую часть пути автобус ехал 2 ч со скоростью 60 км/ч, вторую часть пути он ехал 3ч со скоростью 55 км/ч. Какое расстояние проехал автобус?​

Answer 1

ответ:285км

Пошаговое объяснение:

2×60=120(km) проехал за 2 часа

3×55=165(км) проехал за 3 часа

120+165=285(км)

ответ 285км автобус поехал за все время

Answer 2

Ответ:

285 км

Пошаговое объяснение:

1). 2*60=120 км - 1-я часть пути

2). 3*55=165 км - 2-я часть пути

3). 120+165=285 км - расстояние, которое проехал автобус.

( А можно было просто составить выражение 2*60+3*55=120+165=285 км)

Answer 3

Problem Analysis

To find the distance traveled by the bus, we need to calculate the distance traveled in the first part of the journey and the distance traveled in the second part of the journey, and then add them together.

Calculation

Let's calculate the distance traveled in each part of the journey.

In the first part of the journey, the bus traveled for 2 hours at a speed of 60 km/h. Using the formula `distance = speed * time`, we can calculate the distance traveled in the first part as follows:

Distance in the first part = Speed in the first part * Time in the first part

Distance in the first part = 60 km/h * 2 hours

In the second part of the journey, the bus traveled for 3 hours at a speed of 55 km/h. Using the same formula, we can calculate the distance traveled in the second part as follows:

Distance in the second part = Speed in the second part * Time in the second part

Distance in the second part = 55 km/h * 3 hours

Finally, we can find the total distance traveled by adding the distances in the first and second parts together:

Total distance = Distance in the first part + Distance in the second part

Calculation Results

Let's calculate the distances using the given values:

Distance in the first part = 60 km/h * 2 hours = 120 km

Distance in the second part = 55 km/h * 3 hours = 165 km

Total distance = 120 km + 165 km = 285 km

Therefore, the bus traveled a total distance of 285 kilometers.

Answer

The bus traveled a total distance of 285 kilometers.
