Question

Два поезда едут навстречу друг к другу из двух пунктов. Скорость одного составляет 3\4 скорости первого. Каково расстояние между пунктами, если они встретились через 2 часа?

Answer 1

Хкм/ч-скорость 1
3/4*хкм/ч-скорость 2
х+3/4х=7/4хкм/ч скорость сближения
7/4*х+2=7/2*х=3,5хкм-расстояние между пунктами

Answer 2

Problem Analysis

We have two trains traveling towards each other from two different points. The speed of one train is 3/4 of the speed of the other train. We need to find the distance between the two points if they meet after 2 hours.

Solution

Let's assume the speed of the first train is x units per hour. Therefore, the speed of the second train is 3/4x units per hour.

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

Distance = Speed × Time

For the first train, the distance traveled in 2 hours is 2x units.

For the second train, the distance traveled in 2 hours is 2(3/4x) = 3/2x units.

Since the two trains are traveling towards each other, the sum of their distances should be equal to the total distance between the two points.

Therefore, we can write the equation:

2x + 3/2x = Total Distance

Simplifying the equation:

4x + 3x = Total Distance

7x = Total Distance

To find the value of x, we need more information. Unfortunately, the given question does not provide any additional information or constraints. Therefore, we cannot determine the exact value of x or the total distance between the two points.

If you have any additional information or constraints, please provide them so that we can assist you further.
