Question

Две электрички выехали одновременно с конечных станций.Через 2ч они встретились продолжили движение каждая в своём направлении .Скорость одной электрички 49км/ч,другой 53км/ч.Каково расстояние между конечными станциями?Какое расстояние будет между ними через 2чпосле встречи?

Answer 1

(49+53)*2=204 (км) расстояние между станциями
49*2=98 (км) пройдет одна электричка после встречи
53*2=106 (км) пройдет другая электричка после встречи
108+98=204 (км) будет через 2 часа после встречи
Ответ: 204 км; 204 км.

Answer 2

Расстояние: 49*2+53*2=98+106=204 км. расстояние после встречи тоже будет 204 км, так как они движутся на постоянной скорости и проехали такое же количество времени

Answer 3

To find the distance between the two terminal stations, we can use the formula:

Distance = Speed x Time

Let's calculate the distance between the terminal stations:

The first train has a speed of 49 km/h, and it travels for 2 hours before meeting the second train. Therefore, the distance covered by the first train is:

Distance of the first train = Speed x Time = 49 km/h x 2 h = 98 km [[1]]

Similarly, the second train has a speed of 53 km/h and also travels for 2 hours before meeting the first train. Therefore, the distance covered by the second train is:

Distance of the second train = Speed x Time = 53 km/h x 2 h = 106 km [[1]]

Since the two trains meet, the sum of the distances covered by both trains will give us the total distance between the terminal stations:

Total distance between the terminal stations = Distance of the first train + Distance of the second train = 98 km + 106 km = 204 km

So, the distance between the terminal stations is 204 km.

Now, let's calculate the distance between the two trains after 2 hours from their meeting point:

Since the first train traveled for 2 hours at a speed of 49 km/h, it would have covered a distance of:

Distance covered by the first train = Speed x Time = 49 km/h x 2 h = 98 km [[1]]

Similarly, the second train also traveled for 2 hours at a speed of 53 km/h, so it would have covered a distance of:

Distance covered by the second train = Speed x Time = 53 km/h x 2 h = 106 km [[1]]

Since the two trains are moving in opposite directions, the distance between them after 2 hours would be the sum of the distances covered by both trains:

Distance between the two trains after 2 hours = Distance covered by the first train + Distance covered by the second train = 98 km + 106 km = 204 km

Therefore, the distance between the two trains after 2 hours from their meeting point is 204 km.

Please note that these calculations assume constant speeds for the entire duration of the journey and do not account for any stops or changes in speed along the way.
