Question

Помогите решить задачуС двух станей одновременно навстречу друг другу выехали два поезда. Скорость первого поезда равна 58км/ч, а скорость второго поезда - на 4км/ч больше. Через 4 часа расстояние между поездами было равно 158км. Каково расстояние между станциями?

Answer 1

1 задача.
1)40+70=110км/ч общая скорость
2)660:110=6ч они встретятся
3)40*6=240км от одной станции
   70*6=420км от другой станции.

Answer 2

Problem Analysis

We have two trains traveling towards each other. The speed of the first train is 58 km/h, and the speed of the second train is 4 km/h faster than the first train. After 4 hours, the distance between the trains is 158 km. We need to find the distance between the two stations.

Solution

Let's assume that the distance between the two stations is x km.

After 4 hours, the first train has traveled a distance of 58 km/h * 4 h = 232 km. The second train, which is traveling towards the first train, has also traveled a distance of 58 km/h * 4 h = 232 km.

The total distance covered by both trains after 4 hours is 232 km + 232 km = 464 km.

Since the distance between the two trains is 158 km, we can set up the following equation:

x = 464 km - 158 km

Simplifying the equation, we find:

x = 306 km

Therefore, the distance between the two stations is 306 km.
