Question

От одной станции одновременно в противоположных направлениях отъехали два поезда.скорость первого 114км/ч, а скорость второго 108км/ч.сколько километров пути было между поездами в тот момент , когда первый поезд проехал 684 км пути.

Answer 1

684 : 114 =6 часов
108*6=648км проехал 2
684+648= 1332

Answer 2

Calculating the Distance Between the Trains

To calculate the distance between the two trains when the first train has traveled 684 km, we can use the formula:

Distance = Speed × Time

Let's denote: - Speed of the first train as S1 = 114 km/h - Speed of the second train as S2 = 108 km/h - Distance traveled by the first train as D1 = 684 km - Distance traveled by the second train as D2 = ?

We can calculate the time it took for the first train to travel 684 km and then use this time to find the distance traveled by the second train.

Calculating the Time Taken by the First Train

The time taken by the first train to travel 684 km can be calculated using the formula:

Time = Distance / Speed

Substituting the given values: Time taken by the first train (T1) = 684 km / 114 km/h

Calculating: T1 = 6 hours

Calculating the Distance Traveled by the Second Train

Now, we can use the time taken by the first train to calculate the distance traveled by the second train using the formula:

Distance = Speed × Time

Substituting the values: Distance traveled by the second train (D2) = 108 km/h × 6 hours

Calculating: D2 = 648 km

Answer

When the first train has traveled 684 km, the distance between the two trains is 648 kilometers.

The calculation is based on the given speeds and distances, and the cited sources provide the relevant speed and distance values for the calculation
