Question

СРОЧНОООО!!!! Треть пути автомобиль проехал со скоростью 60 км / ч. Вычисли скорость движения автомобиля на втором участке пути, если его средняя скорость 80 км / ч

Answer 1

Calculation of the Speed on the Second Segment of the Journey

To calculate the speed of the car on the second segment of the journey, we can use the formula:

Average Speed = Total Distance / Total Time

In this case, we know that the car traveled the first segment with a speed of 60 km/h and the average speed for the entire journey is 80 km/h. Let's assume the total distance is D and the time taken for the first segment is T1.

We can calculate the time taken for the second segment, T2, using the formula:

T2 = D - T1

Now, we can substitute the values into the formula for average speed:

80 km/h = D / (T1 + T2)

Simplifying the equation, we get:

80 km/h = D / (T1 + D - T1)

80 km/h = D / D

80 km/h = 1

This equation is not possible, as it implies that the average speed for the entire journey is equal to the speed on the second segment. Therefore, there seems to be an error in the given information or calculation.

Please double-check the values provided and ensure that the question is accurate. If you have any additional information or clarification, I would be happy
