Answer

Distance -time graph can be shown as under:

We deal with distance – time graph while studying the motion of bodies. If we record distance and time for the motion of a body and plot the same data on rectangular graph, we will obtain distance – time graph corresponding to the motion of that body.

Suppose a bus driver is driving at a constant speed which is indicated by the speedometer and the driver measures the time taken by the bus for every kilometer. The driver notices that the bus travels 1 kilometer in every 2 minutes. He prepares the data table after this so that he has a clear understanding for everything and then draws the  graph as shown below.

The following things can be concluded now:

1. If distance time graph is a straight line then the motion is uniform.
2. If distance time graph of any body is given, its speed can be calculated using the slope of the graph.
3. The slope of the straight line graph is same irrespective of the interval which is chosen. This implies that the speed of an object under uniform motion remains constant.
