Two trains left the two cities to meet each other. After the first train traveled 169 km and the second one 140 km. Distance between cities?

The problem can be solved with one step, without affecting the equation or formula, but before we proceed, we write out all the data necessary for this.
It has already been said that one traveled 169 and the other 140 kilometers. There are 50 kilometers between them.
Now we can answer the question of the problem. Let’s calculate the distance between cities, and in order to do this, it is necessary to add up all the known routes.
140 + 50 + 169 = 359 (kilometers) – from one city to another.
Answer: there are 359 kilometers between the two cities.
