Question

С двух станций на встречу друг другу вышли 2 поезда, скорость первого 68 км/ч. А второго 74 км/ч. Через 12 ч. когда поезда ещё не встретились расстояние между ними составило 66 км. Найдите расстояние между станциями.

Answer 1

1) 68×12=816-км проехал 1поезд
2)74×12=888-км проехал 2поезд
3)816×888=1704-км проехало 2поезда
4)1704+66=1870-км от одной до другой станцыии

Answer 2

Problem Analysis

We have two trains that are traveling towards each other. The first train has a speed of 68 km/h, and the second train has a speed of 74 km/h. After 12 hours, when the trains have not yet met, the distance between them is 66 km. We need to find the distance between the stations.

Solution

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

After 12 hours, the first train has traveled a distance of 68 km/h * 12 h = 816 km. The second train has traveled a distance of 74 km/h * 12 h = 888 km.

The total distance covered by both trains after 12 hours is 816 km + 888 km = 1704 km.

Since the distance between the two trains is 66 km, the remaining distance between the two stations is d - 66 km.

Now, we can set up the following equation to solve for d:

d - 66 km = 1704 km

Simplifying the equation:

d = 1704 km + 66 km d = 1770 km

Therefore, the distance between the two stations is 1770 km.

Answer

The distance between the two stations is 1770 km.
