Question

Два поезда отошли одновременно от одной станции в противоположных направлениях со скоростью 114 км/ч . первый из них проехал 684 км. на каком расстояние друг от друга в этот момент находились поезда?

Answer 1

684*2=1368 км
ответ:на расстоянии 1368 км

Answer 2

Problem Analysis

We are given two trains that depart simultaneously from the same station in opposite directions. The first train travels at a speed of 114 km/h and has already traveled 684 km. We need to determine the distance between the two trains at this moment.

Solution

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

Distance = Total Distance - Distance Traveled by the First Train

The total distance covered by both trains is equal to the sum of the distances traveled by each train. Since the trains are moving in opposite directions, the total distance is the sum of the distances traveled by each train.

Let's calculate the distance between the two trains:

Total Distance = Distance Traveled by the First Train + Distance Traveled by the Second Train

Total Distance = 684 km + Distance Traveled by the Second Train

Now, we need to find the distance traveled by the second train. We can use the formula:

Distance = Speed × Time

Since the speed of the second train is also 114 km/h, we can calculate the time it takes for the second train to cover the distance traveled by the first train:

Time = Distance Traveled by the First Train / Speed of the Second Train

Substituting the given values:

Time = 684 km / 114 km/h

Now, we can calculate the distance traveled by the second train:

Distance Traveled by the Second Train = Speed of the Second Train × Time

Substituting the given values:

Distance Traveled by the Second Train = 114 km/h × (684 km / 114 km/h)

Simplifying the equation:

Distance Traveled by the Second Train = 684 km

Finally, we can calculate the distance between the two trains:

Distance = Total Distance - Distance Traveled by the First Train

Distance = (684 km + 684 km) - 684 km

Distance = 684 km

Therefore, at this moment, the two trains are 684 km apart from each other.

Answer

At this moment, the two trains are 684 km apart from each other.
