Question

расстояние между станциями Вороново и Сорокино равно 12,5км.Электричка отошла от станции Вороново в 12ч26мин и прибыла на станцию Сорокино в 12ч38 мин.Скакой скоростью прошла электричка расстояние между этими двумя станциями?Выразитескорость электрички в километрах в час.

Answer 1

12ч38м-12  ч26  м =12минут
12,5:12=104км/ч

Answer 2

Calculating the Speed of the Train

To calculate the speed of the train, we can use the formula:

Speed = Distance / Time

Given: - Distance between stations (Voronovo and Sorokino) = 12.5 km - Departure time from Voronovo = 12:26 - Arrival time at Sorokino = 12:38

First, let's calculate the time taken by the train to travel from Voronovo to Sorokino.

Calculating the Time Taken

The departure time from Voronovo is 12:26, and the arrival time at Sorokino is 12:38. To calculate the time taken, we can subtract the departure time from the arrival time.

12:38 - 12:26 = 12 minutes

So, the train took 12 minutes to travel from Voronovo to Sorokino.

Calculating the Speed

Now, we can use the formula to calculate the speed of the train:

Speed = Distance / Time

Substituting the given values: Speed = 12.5 km / 12 minutes

To express the speed in kilometers per hour, we need to convert the time from minutes to hours. There are 60 minutes in an hour, so:

12 minutes = 12 / 60 = 0.2 hours

Now, we can calculate the speed:

Speed = 12.5 km / 0.2 hours

Final Calculation

Let's calculate the final speed of the train:

Speed = 12.5 km / 0.2 hours = 62.5 km/h

So, the speed of the train between Voronovo and Sorokino is 62.5 kilometers per hour.
