Two pedestrians walk at each other, one goes 2 m / s and the second 5m / s

Two pedestrians walk at each other, one goes 2 m / s and the second 5m / s after how long do they meet if the distance between them is 120m?

Two pedestrians walk towards each other. The speed of one is 2 m / s, the speed of the second is 5 km / h. It is known that there are 120 meters between pedestrians. Let’s find the time after which they will meet.

Distance is the product of the speed of movement and the time spent on the path.

Since people walk towards each other, the distance decreases every second by an amount equal to the sum of the pedestrian speeds. Let’s find the time after which they will meet:

t = S / (V1 + V2) = 120/7 = 17 1/7 s.
