Question

и двух городов растояние между которыми 880 км одновременно навстречу друг другу вышли два поезда.Скорость первого поезда 50 км в час скорость второго 60 км в час.Через сколько часов поезда встретятся

Answer 1

Problem Analysis

We are given that two trains are traveling towards each other from two different cities. The distance between the cities is 880 km. The first train is traveling at a speed of 50 km/h, and the second train is traveling at a speed of 60 km/h. We need to determine how many hours it will take for the trains to meet.

Solution

To solve this problem, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two trains since they are traveling towards each other.

Let's calculate the time it will take for the trains to meet.

Calculation

The distance between the two cities is 880 km. The speed of the first train is 50 km/h. The speed of the second train is 60 km/h.

The relative speed of the two trains is the sum of their speeds: 50 km/h + 60 km/h = 110 km/h.

Using the formula, we can calculate the time it will take for the trains to meet:

Time = Distance / Relative Speed

Time = 880 km / 110 km/h

Time = 8 hours

Therefore, the trains will meet after 8 hours.

Answer

The trains will meet after 8 hours.
