Question

Расстояние от Перми до Казани ,равное 723 км,автомобиль проехал за 13 ч.Первые 9 ч.он ехал со скоростью 55 км./ч.Опредили скорость автомобиля в оставшееся время

Answer 1

Calculation of the Remaining Time

To determine the speed of the car for the remaining time, we can use the formula:

Speed = Distance / Time

Given that the distance from Perm to Kazan is 723 km and the car traveled for 13 hours, we can calculate the speed for the remaining time.

The car traveled for the first 9 hours at a speed of 55 km/h. To find the remaining time, we subtract 9 hours from the total travel time of 13 hours:

Remaining Time = Total Time - First 9 Hours

Remaining Time = 13 hours - 9 hours

Remaining Time = 4 hours

Now, we can calculate the speed for the remaining time using the formula mentioned earlier:

Speed = Distance / Time

Speed = 723 km / 4 hours

Speed = 180.75 km/h

Therefore, the speed of the car for the remaining time is approximately 180.75 km/h.
