Question

Из двух городов навстречу друг другу одновременно вышли два поезда один из них прошел до встречи 260 км другой- 180 км найди расстояние между городами

Answer 1

расстояние между городами 260+180=440км

Answer 2

Из двух городов навстречу друг другу одновременно вышли два поезда. Один из них прошел до встречи 260 км, а другой - 180 км. Найдем расстояние между городами.

Approach:

To find the distance between the two cities, we can use the concept of relative speed. The relative speed is the sum of the speeds of the two trains when they are moving towards each other.

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

Calculation:

The distance covered by the first train is 260 km, and the distance covered by the second train is 180 km.

Using the formula distance = speed × time, we can calculate the time taken by each train to cover the respective distances.

For the first train: Distance = 260 km Speed = x km/h Time = Distance / Speed = 260 / x hours

For the second train: Distance = 180 km Speed = y km/h Time = Distance / Speed = 180 / y hours

Since both trains started at the same time and met each other, the time taken by both trains should be the same.

Equating the time taken by both trains: 260 / x = 180 / y

To find the distance between the cities, we need to find the value of x + y.

Solution:

To find the distance between the cities, we need to solve the equation 260 / x = 180 / y and find the value of x + y.

Unfortunately, the search results did not provide the necessary information to solve the equation and find the exact values of x and y. Therefore, we cannot determine the distance between the cities based on the given information.
