Two pedestrians left two points towards each other, the distance between which is 30 km. The speed of one is 6 km / h, and the other is 4 km / h. In how many hours they will meet. What is the distance between them in 2 hours?
30 km is the distance between two points.
6 km / h – the rate of movement of one pedestrian.
4 km / h – the pace of movement of another pedestrian.
6 + 4 = 10.
10 km / h – the rate of convergence of pedestrians.
30/10 = 3.
3 hours two pedestrians will meet.
10 * 2 = 20.
20 km – pedestrians will walk together.
30 – 20 = 10.
10 km will be the distance between pedestrians in 2 hours.
Solution: After 3 hours.
