Explain the situations represented by the following distance-time graph.

उत्तर
Here x-axis represents time and y-axis represents distance.
In the first graph, we observe that when time changes, distance also varies at the same rate.
When we move along time axis away from the origin, then the graph is strictly increasing.
Hence, the object is moving at a uniform speed.
