Question

Помогите срочно! Электропоезд отправился из города в 9 ч 15 мин и прибыл на конечную станцию в 10 ч 12 мин.По пути он делал остановку на каждой из 12 промежуточных станций в среднем на 35 сек. Сколько времени электропоезд находился в движении от города до конечной станции?С какой скоростью он двигался ,если известно ,что расстояние от города​ до конечной станции 48 ем? Пожалуйста помогите !!

Answer 1

52 минуты поезд ездил

Answer 2

1)12*35=7(минут)-на все остановки
2)10ч12мин-9ч15 мин=57(минут)-время на весь затраченный путь
3)57-7=50(минут)-ехал,без остановки
4)50мин-48 км
60 мин-х км
х=57,6(км/ч)
Ответ:57,6 км/ч

Calculating the Time Spent in Motion

To calculate the time the electric train spent in motion from the city to the final station, we can follow these steps:

1. Calculate the total time taken for the journey: - The train departed from the city at 9:15 and arrived at the final station at 10:12. - We need to find the total time taken for the journey.

2. Calculate the total time spent on stops: - The train made stops at each of the 12 intermediate stations, with an average stop time of 35 seconds. - We need to calculate the total time spent on stops.

3. Subtract the total stop time from the total journey time: - By subtracting the total stop time from the total journey time, we can find the time the train spent in motion.

Calculation Steps

1. Calculate the total journey time: - The total journey time can be calculated by finding the difference between the departure and arrival times.

The total journey time is 57 minutes.

2. Calculate the total time spent on stops: - The total time spent on stops can be calculated by multiplying the number of stops by the average stop time.

The total time spent on stops is 7 minutes.

3. Subtract the total stop time from the total journey time: - By subtracting the total stop time from the total journey time, we can find the time the train spent in motion.

The time the train spent in motion is 50 minutes.

Calculating the Speed of the Electric Train

To calculate the speed of the electric train, we can use the formula: speed = distance / time.

1. Calculate the speed of the electric train: - The distance from the city to the final station is given as 48 km. - We already calculated the time the train spent in motion as 50 minutes.

The speed of the electric train is 57.6 km/h.

Therefore, the electric train was in motion for 50 minutes and traveled at an average speed of 57.6 km/h from the city to the final station.
