Question

Из двух городов одновременно навстречу друг другу вышли два поезда и встретились через 2 часа. Скорость одного из них 48 км/ч,а другого на 6 км/ч меньше. Найди расстояние между городами

Answer 1

1) 48 - 6 = 42 км/ч скорость второго поезда
2) 48 + 42 = 90 км/ч скорость сближение поездов
3) 90 * 2 = 180 км расстояние между городами

Answer 2

Problem Analysis

We are given that two trains start from two different cities simultaneously and meet each other after 2 hours. The speed of one train is 48 km/h, while the speed of the other train is 6 km/h less. We need to find the distance between the two cities.

Solution

Let's assume the speed of the slower train is x km/h. Since the speed of the other train is 6 km/h more, its speed will be (x + 6) km/h.

We know that distance = speed × time.

For the slower train: Distance covered by the slower train = x km/h × 2 hours.

For the faster train: Distance covered by the faster train = (x + 6) km/h × 2 hours.

Since the two trains meet each other, the sum of their distances covered will be equal to the total distance between the two cities.

Therefore, the equation becomes: x km/h × 2 hours + (x + 6) km/h × 2 hours = total distance.

Simplifying the equation: 2x + 12 = total distance.

To find the total distance, we need to know the value of x. However, the problem does not provide any additional information to determine the value of x.

Therefore, we cannot find the exact distance between the two cities without knowing the value of x.
