Question

Из городов А и В находящихся на расстоянии 175 км друг от друга,вышли одновременно в противоположных направлениях два поезда. Один шел со скоростью 50 км/ч, другой 55 км/ч на каком расстоянии будут эти два поезда через 6 часов после начала движения?

Answer 1

1)50+55=105 км/час-скорость расхождения автомобилей
2)105*6=630 км -пройдут оба за 6 часов
3)630+175=805 км-станет между ними 

Answer 2

Problem Analysis

We are given two cities, A and B, which are 175 km apart. Two trains start simultaneously from these cities in opposite directions. The first train travels at a speed of 50 km/h, while the second train travels at a speed of 55 km/h. We need to determine the distance between the two trains after 6 hours.

Solution

To find the distance between the two trains after 6 hours, we can calculate the total distance covered by both trains and then subtract the initial distance between the cities.

Let's calculate the distance covered by each train after 6 hours.

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

Similarly, the second train travels at a speed of 55 km/h for 6 hours, so the distance covered by the second train is: Distance of the second train = Speed of the second train × Time = 55 km/h × 6 h = 330 km.

Now, let's calculate the distance between the two trains after 6 hours: Distance between the two trains = Distance covered by the first train + Distance covered by the second train - Initial distance between the cities = 300 km + 330 km - 175 km = 455 km.

Therefore, the two trains will be 455 km apart after 6 hours.

Answer

The two trains will be 455 km apart after 6 hours.
