Question

Длина маршрута, который автобус проезжает за 7/10 часа,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

1)сколько времени едит автобус без остановок
$20,25:45=0,45$час
всего в пути с остановками 0,7 часа
 значит на остановки приходится 0,7-0,45=0,25 часа
всего 10 остановок,значит на каждую приходится 0,25:10=0,025 часа или 1,5 мин(60*0,025=1,5)

Answer 2

Calculation of Bus Route Length

To find the length of the bus route, we are given that the bus travels for 7/10 hours and covers a distance of 20 1/4 km. We can calculate the average speed of the bus using the formula:

Average Speed = Total Distance / Total Time

Using this formula, we can find the total distance covered by the bus:

Total Distance = Average Speed * Total Time

Given that the average speed of the bus is 45 km/h and the total time is 7/10 hours, we can calculate the total distance:

Total Distance = 45 km/h * (7/10) hours

Now, let's calculate the total distance covered by the bus:

Total Distance = 45 km/h * (7/10) hours = 31.5 km

Therefore, the total distance covered by the bus is 31.5 km.

Calculation of Time Spent at Each Stop

Next, we need to calculate the time spent at each stop. We are given that the bus makes 10 stops and spends the same amount of time at each stop.

To find the time spent at each stop, we can divide the total time spent on stops by the number of stops. The total time spent on stops can be calculated by subtracting the time spent traveling from the total time:

Total Time Spent on Stops = Total Time - Time Spent Traveling

Given that the total time is 7/10 hours and the bus travels for this entire duration, the time spent traveling is 7/10 hours.

Total Time Spent on Stops = (7/10) hours - (7/10) hours = 0 hours

Since the bus spends 0 hours traveling, the entire duration of 7/10 hours is spent at stops.

To find the time spent at each stop, we divide the total time spent on stops by the number of stops:

Time Spent at Each Stop = Total Time Spent on Stops / Number of Stops

Given that there are 10 stops, we can calculate the time spent at each stop:

Time Spent at Each Stop = 0 hours / 10 stops = 0 hours

Therefore, the bus spends 0 hours at each stop.

Summary

To summarize, the length of the bus route is 31.5 km. The bus spends 0 hours at each of the 10 stops it makes along the route.
