Question

Из двух городов,расстояние между которыми 450 км, одновременно вышли навстречу друг другу два поезда.Один прошёл 120 км, а другой - на 35 км больше. На каком расстоянии друг от друга находятся поезда?

Answer 1

1) 120+35=155(км) 2 поезд
2) 155+120=275( км) проехали вместе.
3) 450-275= 175 ( км)

Answer 2

1) 120+35=155(км) - прошёл 2 поезд
2) 120+155=275(км) - они прошли всего
3) 450-275=175(км)
Ответ: расстояние между ними 175 км.

Answer 3

Problem Analysis

We have two trains traveling towards each other from two cities that are 450 km apart. One train has traveled 120 km, while the other train has traveled 35 km more than the first train. We need to find the distance between the two trains.

Solution

Let's denote the distance traveled by the first train as x km. According to the problem, the second train has traveled 35 km more than the first train, so the distance traveled by the second train is x + 35 km.

Since the two trains are traveling towards each other, the sum of the distances traveled by both trains should be equal to the total distance between the two cities, which is 450 km.

Therefore, we can write the equation:

x + (x + 35) = 450

Simplifying the equation, we get:

2x + 35 = 450

Subtracting 35 from both sides, we have:

2x = 415

Dividing both sides by 2, we get:

x = 207.5

So, the first train has traveled 207.5 km, and the second train has traveled 207.5 + 35 = 242.5 km.

Therefore, the distance between the two trains is 207.5 + 242.5 = 450 km.

Answer

The two trains are currently located 450 km apart from each other.
