From two cities, two trains set off to meet each other at the same time. they met after 7 hours.

From two cities, two trains set off to meet each other at the same time. they met after 7 hours. the speed of the first train is 60 km / h, and the speed of the second is 80 km / h. find the distance between cities.

Let’s write down the general formula for finding the path:
S = V * t (where S is the path; V is the speed; t is the time).
Let’s find the total speed of the two trains:
60 + 80 = 140 (km / h) – the total speed of the two trains.
At a given speed, they covered some distance in 7 hours.
We substitute the data into the above formula for finding the path, and find what path was between the two trains initially:
S = 140 * 7 = 980 (km) – the distance between the two cities.
Answer: 980 km.
