Men are running along a road at 15 km/hr behind one another at equal intervals of 20 m. Cyclists are riding in the same direction at 25 km/hr at equal intervals of 30 m. at what speed an observer must travel along the road in opposite direction so that whenever he meets a runner , he also meets a cyclist?
