Two cars drove towards each other in settlements located at a distance of 280 km. The speed of one is 60 km / h, and the other is 80 km / h. How many hours will the cars meet.
They will meet in the same time, let’s take it for x
So the first car drove 60x before the meeting
And the second is 80x
The sum of their path to the meeting is equal to the distance between them
Let’s make the equation:
60x + 80x = 280
140x = 280
x = 2
