Question

реши задачу два поезда отошли одновременно от одной станции в противоположных направлениях со скоростью 114км/ч и 108км/ч. Первый из них проехал 684 км. На каком расстоянии друг от друга в этот момент находились поезда? Помогите решить пожалуйсто надо срочно!!!!??

Answer 1

684/114=6 часов ехал первый поезд и второй тоже

108*6=648 км проехал второй

 

684+ 648=1332км на таком расстоянии

Answer 2

Problem Analysis

We are given two trains that depart simultaneously from the same station in opposite directions. The first train has a speed of 114 km/h, and the second train has a speed of 108 km/h. We are also given that the first train has traveled a distance of 684 km. We need to determine the distance between the two trains at this moment.

Solution

To solve this problem, we can use the formula: distance = speed * time.

Let's assume that the time taken by the first train to travel the given distance is 't' hours. Since the two trains are moving in opposite directions, the distance covered by the second train in the same time 't' will be the sum of the distances covered by both trains.

Let's calculate the distance covered by the second train in 't' hours: Distance covered by the second train = (Speed of the second train) * (Time taken by the first train to cover the given distance)

Now, let's substitute the given values into the formula: Distance covered by the second train = 108 km/h * t hours

Since the two distances are equal, we can set up the following equation: Distance covered by the first train = Distance covered by the second train

684 km = 108 km/h * t hours

To find 't', we can rearrange the equation: t = 684 km / 108 km/h

Now, let's calculate 't': t = 6 hours

Therefore, the two trains were 684 km apart at this moment.

Answer

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