Question

Длина маршрута автобуса равна 20 1\4 км. Рейс длится 7\10 часа. Автобус движется со скоростью 45 км\ч и делает 10 остановок. Сколько времени в среднем затрачивается на одну остановку?

Answer 1

1) S = 20 1/4 = 20,25 (км) - длина маршрута; v = 45 (км/ч) - скорость автобуса; t = 20,25 : 45 = 0,45 (ч) - время проезда без остановок;
2) 7/10 = 0,7 (ч) - время проезда с остановками;
3) 0,7 - 0,45 = 0,25 (ч) - столько времени уходит на 10 остановок;
4) 0.25 ч = 0,25 * 60 = 15 минут
15 : 10 = 1,5 (мин.) - среднее время одной остановки.
Ответ: на одну остановку в среднем затрачивается полторы минуты.

Answer 2

Calculation of Time Spent on Each Stop

To calculate the average time spent on each stop, we need to determine the total time spent on the journey and the number of stops made by the bus.

Given information: - Length of the bus route: 20 1/4 km - Duration of the trip: 7/10 hours - Speed of the bus: 45 km/h - Number of stops made: 10

To find the total time spent on the journey, we can use the formula: time = distance / speed.

Using this formula, we can calculate the total time spent on the journey: - Distance: 20 1/4 km - Speed: 45 km/h

Total time spent on the journey = (20 1/4) km / 45 km/h

To calculate the average time spent on each stop, we need to divide the total time spent on the journey by the number of stops made.

Let's calculate the total time spent on the journey and the average time spent on each stop.

Calculation:

1. Convert the length of the bus route to a decimal: - 20 1/4 km = 20.25 km

2. Calculate the total time spent on the journey: - Total time = Distance / Speed - Total time = 20.25 km / 45 km/h

Total time spent on the journey = 0.45 hours

3. Calculate the average time spent on each stop: - Average time = Total time / Number of stops - Average time = 0.45 hours / 10

Average time spent on each stop = 0.045 hours

Therefore, on average, the bus spends approximately 0.045 hours (or 2.7 minutes) at each stop.
