The distance between the two villages is 14 km, from these villages 2 pedestrians came out at the same time towards each other. The speed of the first is 4 km / h, and the second is 3 km / h. How many hours will the pedestrians meet?

First, we determine the distance that both pedestrians will travel in one hour, that is, we find out their speed of convergence. To do this, add their two speeds together:
1) 3 km / h + 4 km / h = 7 km / h – the speed of convergence of pedestrians.
Next, we find out how many hours it will take for them to cover the distance specified in the problem statement, if we divide this distance by their approach speed:
2) 14 km / 7 km / h = 2 hours – meeting time for pedestrians.
Bottom line: the meeting of two pedestrians will take place two hours after their start.
