Question

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 с. Сколько времени электропоезд находился в движении от города до конечной станции 48 км. (Вырази расстояние в метрах, а время в минутах.) С краткой записью!!!

Answer 1

10 ч 12 мин = 612 минут
9 ч 15 мин = 555 мин

1) 612 - 555 = 57 (мин) - был в пути с остановками
2) 12 * 35 = 420 с = 7 (мин) - потратил на остановку
3) 57 - 7 = 50 (мин) - находился в движении от города
4) 48 км = 48000 (м)
5) 48000 : 50 = 960 (м/мин) - 

Answer 2

Calculation of the Total Travel Time

To calculate the total travel time of the electric train from the city to the final station, we need to consider the departure time, the arrival time, and the time spent at each intermediate station.

The train departed from the city at 9:15 AM and arrived at the final station at 10:12 AM. The total travel time can be calculated by subtracting the departure time from the arrival time:

Total travel time = Arrival time - Departure time

Let's convert the departure and arrival times to minutes for easier calculation:

Departure time: 9:15 AM = 9 * 60 + 15 = 555 minutes Arrival time: 10:12 AM = 10 * 60 + 12 = 612 minutes

Now we can calculate the total travel time:

Total travel time = 612 minutes - 555 minutes = 57 minutes

So, the electric train was in motion from the city to the final station for a total of 57 minutes.

Calculation of the Total Stopping Time

The train made stops at each of the 12 intermediate stations, with an average stop time of 35 seconds at each station. To calculate the total stopping time, we need to multiply the average stop time by the number of intermediate stations:

Total stopping time = Average stop time * Number of intermediate stations

Average stop time: 35 seconds Number of intermediate stations: 12

Now we can calculate the total stopping time:

Total stopping time = 35 seconds * 12 = 420 seconds

Since we need to express the distance in meters and the time in minutes, we need to convert the total stopping time from seconds to minutes:

Total stopping time = 420 seconds / 60 = 7 minutes

So, the electric train spent a total of 7 minutes in stopping time at the intermediate stations.

Calculation of the Distance Traveled

The distance between the city and the final station is given as 48 km. To express the distance in meters, we need to multiply it by 1000:

Distance = 48 km * 1000 = 48,000 meters

Summary

To summarize the information:

- The electric train was in motion from the city to the final station for a total of 57 minutes. - The electric train spent a total of 7 minutes in stopping time at the intermediate stations. - The distance traveled by the electric train was 48,000 meters.
