Question

Расстояние от Перми до Казани равное 723км автомобиль проехал за 13 часов. Первые 9 часов он ехал со скоростью 55 км в час. Определить скорость автомобиля оставшегося времени.

Answer 1

Пошаговое объяснение:

9 * 55 = 495 километров.

13 - 9 = 4 часа.

723 - 495 = 228 километров.

228 / 4 = 57 километров.

Answer 2

Ответ:

57 км/ч

Пошаговое объяснение:

1) 55*9=495 (км)-за первые 9 часов

2) 723-495=228 (км)-вторая часть пути

3) 13-9=4 (ч)- время на вторую часть пути

4) 228÷4=57 (км/ч)-скорость авто на второй части пути.

Answer 3

Calculation of Remaining Time Speed

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 first 9 hours using the formula:

Speed = Distance / Time = 723 km / 9 hours = 80.33 km/h.

To find the speed for the remaining time, we need to subtract the time traveled in the first 9 hours from the total time of 13 hours:

Remaining Time = Total Time - Time Traveled = 13 hours - 9 hours = 4 hours

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

Speed = Distance / Time = 723 km / 4 hours = 180.75 km/h

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