Question

Два поезда отошли Одновременно навстречу друг другу со станций расстояние между которыми 520 километров один поезд прошел до встречи 250 километров со скоростью 50 километров в час с какой скоростью шел второй поезд

Answer 1

250/50=5 часов до встречи
520-250=270 км - прошел второй  поезд
270/5=54км/ч - скорость второго поезда

Answer 2

Problem Setup

Two trains are traveling towards each other from stations that are 520 kilometers apart. The first train has traveled 250 kilometers at a speed of 50 kilometers per hour. We need to find the speed of the second train.

Calculation

Let's calculate the speed of the second train using the given information.

The time taken by the first train to cover 250 kilometers at a speed of 50 kilometers per hour can be calculated using the formula: $$ \text{Time} = \frac{\text{Distance}}{\text{Speed}} $$

So, the time taken by the first train is: $$ \text{Time} = \frac{250 \text{ km}}{50 \text{ km/hr}} = 5 \text{ hours} $$

Now, we can use the time taken by the first train to find the speed of the second train using the formula: $$ \text{Speed} = \frac{\text{Distance}}{\text{Time}} $$

The distance remaining for the second train to cover is: $$ \text{Distance remaining} = 520 \text{ km} - 250 \text{ km} = 270 \text{ km} $$

So, the speed of the second train is: $$ \text{Speed} = \frac{270 \text{ km}}{5 \text{ hours}} = 54 \text{ km/hr} $$

Answer

Therefore, the speed of the second train is 54 kilometers per hour.
