Question

Автомашина шла 3 ч со скоростью 53,5 км ч,2 ч со скоростью 62,3 км ч и со скоростью 48,2 км ч Найдите среднюю от двигателя автомашины на всем пути

Answer 1

53.5*3=160.5 км первая часть пути
62.3*2=124.6 км вторая часть пути
160.5+124.6=285.1 км весь путь
3+2=5 ч. все время
285.1:5=57.02 км/ч средняя скорость

Answer 2

Calculation of Average Speed

To find the average speed of the car over the entire journey, we need to calculate the total distance traveled and the total time taken.

Given the following information:

- The car traveled for 3 hours at a speed of 53.5 km/h. - The car traveled for 2 hours at a speed of 62.3 km/h. - The car traveled for an unspecified amount of time at a speed of 48.2 km/h.

We can calculate the total distance traveled by multiplying the time traveled at each speed by the corresponding speed and summing them up.

Total distance = (3 hours * 53.5 km/h) + (2 hours * 62.3 km/h) + (x hours * 48.2 km/h)

To calculate the total time taken, we need to know the value of 'x' (the time traveled at 48.2 km/h). Unfortunately, the given information does not provide the value of 'x'. Therefore, we cannot calculate the exact average speed without this information.

If you have the value of 'x', please provide it so that we can calculate the average speed.
