Question

Два поезда вышли одновременно навстречу друг другу из двух городов, расстояние между ними которыми 650км. первый поезд ехал со скоростью 62км/ч и проехал до встречи 310км. с какой скоростью ехал второй поезд

Answer 1

1)310÷62=5 часов были в пути оба поезда
2)650-310=340 км прошёл второй поезд
3) 340÷5=68 км/час скорость второго поезда

Answer 2

Способ 1
-----------------------------------------------
1)650:5=130(км/ч)-Скорость 1 поезда
2)130-62=68(км/ч)

Способ 2
-----------------------------------------------
1)62*5=310(км)-Проехал 1 поезд
2)650-310=340(км)-Проехал 2 поезд
3)240:5=68(км)

Answer 3

Problem Analysis

We have two trains traveling towards each other from two different cities. The distance between the cities is 650 km. The first train travels at a speed of 62 km/h and has traveled 310 km before the meeting. We need to find the speed of the second train.

Solution

Let's assume the speed of the second train is x km/h.

The first train has traveled 310 km, so the remaining distance for the second train to cover is 650 km - 310 km = 340 km.

We can use the formula distance = speed × time to find the time it takes for the second train to cover the remaining distance.

For the first train: - Distance = 310 km - Speed = 62 km/h - Time = Distance / Speed = 310 km / 62 km/h = 5 hours

For the second train: - Distance = 340 km - Speed = x km/h - Time = Distance / Speed = 340 km / x km/h = 5 hours

Since both trains take the same amount of time to cover their respective distances, we can set up the equation:

5 hours = 5 hours

Now we can solve for the speed of the second train:

340 km / x km/h = 310 km / 62 km/h

Cross-multiplying:

340 km * 62 km/h = 310 km * x km/h

Simplifying:

21,080 km*km/h = 31,310 km*km/h

Dividing both sides by km*km/h:

21,080 km/h = 31,310 km/h

Therefore, the speed of the second train is 31,310 km/h.

Answer

The second train was traveling at a speed of 31,310 km/h.
