Question

Поезд отправился из Санкт Петербурга в 23 ч 15 мин и прибыл в Москву в 6 ч 25 мин следующего дня. по пути он сделал 2 остановки: на станции Бологое и в городе Твери, по 5 мин каждая. с какой скоростью двигался этот поезд, если он прошел 651 км?

Answer 1

1)24ч00мин-23ч15мин+6ч25мин=7ч10мин
2)7ч10мин-2×5мин=7часов поезд двигался
3)651:7=93км/ч-скорость поезда

Answer 2

Поезд был в пути 7 часов

651 :7 = 93 км/час - скорость поезда 

Answer 3

Calculation of the Train's Speed

To calculate the speed of the train, we need to determine the time it took for the train to travel from St. Petersburg to Moscow and the distance covered.

The train departed from St. Petersburg at 23:15 and arrived in Moscow at 6:25 the next day. This means the total travel time was 7 hours and 10 minutes.

The train made two stops along the way: one at the Bologoye station and another in the city of Tver, each lasting 5 minutes.

To calculate the distance covered, we need to subtract the distances of the two stops from the total distance between St. Petersburg and Moscow.

Unfortunately, the search results did not provide the exact distance between St. Petersburg and Moscow. However, we can still calculate the train's speed using the given information.

Let's assume the train covered a distance of 651 km, as mentioned in the question.

Now, let's calculate the speed of the train:

Step 1: Calculate the total travel time: - Departure time: 23:15 - Arrival time: 6:25 the next day - Total travel time: 7 hours and 10 minutes

Step 2: Calculate the total stoppage time: - Number of stops: 2 - Duration of each stop: 5 minutes - Total stoppage time: 2 stops * 5 minutes = 10 minutes

Step 3: Calculate the net travel time: - Net travel time: Total travel time - Total stoppage time = 7 hours and 10 minutes - 10 minutes = 7 hours

Step 4: Calculate the speed of the train: - Speed = Distance / Time - Speed = 651 km / 7 hours = 93 km/h

Therefore, the train was moving at a speed of 93 km/h.

Please note that the actual distance between St. Petersburg and Moscow may vary, and this calculation is based on the assumption of a 651 km distance.
