Question

Первую половину пути автомобиль двигался со скоростью 40 км\ч. Вторую половину пути автомобиль двигался следующим образом: половину этого расстояния автомобиль проехал со скоростью 60 км\ч, а оставшуюся часть- со скоростью 30 км\ч. Чему равна средняя путевая скорость автомобиля на всем пути?

Answer 1

А не так случаем (40+60+60)/3

Answer 2

Calculating the Average Speed of the Car

To calculate the average speed of the car for the entire journey, we can use the formula:

Average Speed = Total Distance / Total Time

Let's break down the journey into its two parts and calculate the average speed for each part separately.

First Half of the Journey

The car traveled the first half of the distance at a speed of 40 km/h.

Second Half of the Journey

For the second half of the journey, the car traveled half of the remaining distance at 60 km/h and the remaining half at 30 km/h.

Calculating the Average Speed for the Entire Journey

We can calculate the average speed for the entire journey by finding the total distance and the total time taken.

Total Distance

The total distance traveled can be calculated by adding the distances covered in the first and second halves of the journey.

Total Time

The total time taken can be calculated by adding the times taken for the first and second halves of the journey.

Now, let's calculate the average speed of the car for the entire journey using the provided information.
