Two trains leave a railway station at the same time. The first train travels towards west and the second train towards north. The first train travels 5 km/hr faster then the second train. If after two hours they are 50 km. apart, find the average speed of each train.

On a long horizontally moving belt (Fig. 3.26), a child runs to and for 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 a) speed of the child running in the direction of motion of the belt ? b) speed of the child running opposite to the direction of motion of the belt ? c) time taken by the child in (a) and (b) ? Which of the answer alter if motion is viewed by one of the parents ?
