The distance-time graph is plotted below, with time taken on X-axis and distance traveled on Y-axis. As nature of the graph is straight line, the speed remains same throughout the motion. Hence, the motion of the object is uniform motion.

The distance-time graph is plotted below, with time taken on X-axis and distance traveled on Y-axis. As nature of the graph is straight line, the speed remains same throughout the motion. Hence, the motion of the object is uniform motion. The speed constant during the motion. To find the distance travelled by the object in first 1 2 hour ( 30 minutes ) is 25 km . Speed = Distance Time Speed = 25 1 2 = 25 × 2 = 50 km / h Speed in m / s = 50 × 1000 3600 m / s = 13 . 88 m / s
