On a long horizontally moving belt (Fig. 3.26), a child runs to and fro with a speed `9 km h^-1` (with respect to the belt) between his father and mother located 50 m apart on the moving belt. The belt moves with a speed of `4 km h^-1`. For an observer on a stationary platform outside, what is the:- speed of the child running opposite to the direction of motion of the belt ?
