Question

От двух станций растояние между которыми равно 660 км вышли одновременно навстречу друг другу два поезда скорость первого поезда 50км в час найдите скорость второго поезда если поезда встретились через 6 часов

Answer 1

1)50 умножаем на 6 и узнаем сколько пройдет первый поезд за 6 часов= 300 км
2)От общего расстояния отнимаем кол-во км которое прошел первый поезд 660-300=360 и узнаем что за 6 часов второй прошел 360 км
3) 360 делим на 6 получается 60 км в час

Answer 2

1) скорость сближения поездов - 660/6=110 км/час;
2) скорость второго поезда - 110-50=60 км/час.

Answer 3

Problem Analysis

We are given that two trains start from two stations simultaneously and travel towards each other. The distance between the stations is 660 km. The speed of the first train is 50 km/h. We need to find the speed of the second train if the trains meet after 6 hours.

Solution

To solve this problem, we can use the formula: distance = speed × time.

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

The first train travels for 6 hours at a speed of 50 km/h, so the distance covered by the first train is: distance_1 = speed_1 × time = 50 km/h × 6 hours = 300 km.

The second train also travels for 6 hours at a speed of x km/h, so the distance covered by the second train is: distance_2 = speed_2 × time = x km/h × 6 hours = 6x km.

Since the total distance between the two stations is 660 km, we can write the equation: distance_1 + distance_2 = 660 km.

Substituting the values of distance_1 and distance_2, we get: 300 km + 6x km = 660 km.

Simplifying the equation, we have: 6x km = 660 km - 300 km, 6x km = 360 km.

Dividing both sides of the equation by 6, we find: x km = 60 km/h.

Therefore, the speed of the second train is 60 km/h.

Answer

The speed of the second train is 60 km/h.
