Question

От одной станции одновремено отошли в противоположных наплавлениях два электро воза средняя скорость одного 55км/ч а другого 60 км/ч какое расстояние будет между ниме через 3 ч

Answer 1

55 плюс 60 равно 115 (км/ч) — скорость сближения
115 умножить на 3 равно 345 км
ответ: 345 км

Answer 2

Calculation of Distance between Two Trains

To calculate the distance between two trains that departed from the same station in opposite directions, we can use the formula:

Distance = (Speed of Train 1 + Speed of Train 2) × Time

Given that the average speed of one train is 55 km/h and the average speed of the other train is 60 km/h, we can calculate the distance between them after 3 hours.

Using the formula, we have:

Distance = (55 km/h + 60 km/h) × 3 hours

Calculating the sum of the speeds:

Distance = 115 km/h × 3 hours

Simplifying the equation:

Distance = 345 km

Therefore, the distance between the two trains after 3 hours will be 345 kilometers.

Please note that the above calculation assumes that the speeds of the trains remain constant throughout the journey and that there are no external factors affecting their speeds or routes.
