Question

Поезд за 1 час 20 минут проезжает 80км.Сколько проедет он в сутки при 10 остановках, каждая из которых по 7,5 минут?

Answer 1

Calculation of Distance Traveled by the Train in a Day

To calculate the distance traveled by the train in a day, we need to consider the time taken for each stop and the total number of stops.

Given: - The train takes 1 hour and 20 minutes (or 80 minutes) to travel 80 km. - There are 10 stops, and each stop takes 7.5 minutes.

To calculate the total time taken for stops, we multiply the time taken for each stop (7.5 minutes) by the number of stops (10): 7.5 minutes/stop * 10 stops = 75 minutes

To calculate the total time taken for travel, we subtract the time taken for stops from the total time available in a day (24 hours or 1440 minutes): 1440 minutes - 75 minutes = 1365 minutes

To calculate the distance traveled in a day, we use the formula: Distance = Speed * Time

The speed of the train can be calculated by dividing the distance traveled in 80 minutes (80 km) by the time taken (80 minutes): Speed = Distance / Time Speed = 80 km / 80 minutes = 1 km/minute

Finally, we calculate the distance traveled in a day by multiplying the speed of the train by the total time taken for travel in a day (1365 minutes): Distance = Speed * Time Distance = 1 km/minute * 1365 minutes = 1365 km

Therefore, the train will travel 1365 km in a day with 10 stops, each taking 7.5 minutes.
