If the distance between two points on a straight line distance-time graph is 120 meters and the corresponding time interval is 4 seconds, what is the uniform speed?
30 m/s
On a straight-line distance-time graph the speed is uniform and equals distance divided by time.
Speed = 120 m ÷ 4 s = 30 m/s.
Hence, the answer is 30 m/s.
