Question

Длина маршрута, который автобус проезжает за 7/10 ч, равна 20 1/4 км. Автобус движется по маршруту со скоростью 45 км/ч и делает 10 остановок. Сколько времени длится каждая остановка автобуса, если на каждой остановке он стоит одинаковое время?

Answer 1

Весь путь автобуса 20.25 км, а его скорость 45 км/ч, можно узнать сколько времени ему нужно затратить, чтобы проехать этот маршрут без остановок 20.20/45=0.45
0.7-0.45=0.25 - время которое он тратит на 10 остановок
0.25/10=0.025ч(1.5 мин) - время на одну остановку

Answer 2

Calculation of Bus Stop Duration

To calculate the duration of each bus stop, we need to consider the total distance traveled by the bus, the speed at which it is moving, and the number of stops it makes.

Given: - Length of the route covered in 7/10 hours (or 42 minutes): 20 1/4 km - Speed of the bus: 45 km/h - Number of stops: 10

To find the duration of each bus stop, we can divide the total time taken for the journey by the number of stops.

First, let's calculate the total time taken for the journey: - The total distance covered is 20 1/4 km. - The speed of the bus is 45 km/h. - Using the formula `time = distance / speed`, we can calculate the total time taken for the journey.

Total time taken for the journey: - Distance: 20 1/4 km - Speed: 45 km/h

Using the formula `time = distance / speed`: ``` time = 20 1/4 km / 45 km/h ```

To perform the calculation, we need to convert the mixed number (20 1/4) to an improper fraction. The improper fraction equivalent of 20 1/4 is (81/4).

time = (81/4) km / 45 km/h

Simplifying the expression: ``` time = (81/4) / 45 ```

Converting the mixed number to a fraction: ``` time = (81/4) / (45/1) ```

Dividing fractions: ``` time = (81/4) * (1/45) ```

Simplifying the expression: ``` time = 81 / (4 * 45) ```

Calculating the value: ``` time = 81 / 180 ```

Simplifying the fraction: ``` time = 9 / 20 ```

Therefore, the total time taken for the journey is 9/20 hours.

Now, let's calculate the duration of each bus stop by dividing the total time taken for the journey by the number of stops.

Duration of each bus stop: - Total time taken for the journey: 9/20 hours - Number of stops: 10

To find the duration of each bus stop, we can divide the total time taken for the journey by the number of stops.

duration of each bus stop = total time taken for the journey / number of stops

Substituting the values: ``` duration of each bus stop = (9/20) hours / 10 ```

Simplifying the expression: ``` duration of each bus stop = (9/20) / 10 ```

Dividing fractions: ``` duration of each bus stop = (9/20) * (1/10) ```

Simplifying the expression: ``` duration of each bus stop = 9 / (20 * 10) ```

Calculating the value: ``` duration of each bus stop = 9 / 200 ```

Therefore, the duration of each bus stop is 9/200 hours.

Please note that the duration of each bus stop is approximate and may vary depending on factors such as traffic conditions and the efficiency of the bus service.
