The distance covered by a body in motion was recorded after every 1 s or 4 s . The data recorded is mentioned in the table below. Time (s) 0 1 2 3 4 Distance (m) 0 3 6 9 12 Represent the situation graphically and find the speed of the body from the graph.

The graph for the above table is given below: Slope of the graph gives the speed of the object. Slope of the object is given by the formula m = y 2 - y 1 x 2 - x 1 Substituting, m = 12 - 9 4 - 3 = 3 m / s Therefore, the speed of the object is 3 m / s .

Plot a distance time graph for the motion of the body with following data. Time (s) 0 1 2 3 4 5 6 Distance (m) 10 20 30 40 40 50 60

Since the data is for time and distance, the graph is a distance-time graph, where distance is plotted on y-axis and time on x-axis. The plotted graph is shown below:
