Observe the data and answer the following questions.
A table shows the arrival and departure times of a train at stations \(A\), \(B\), and \(C\), and their distances from \(A\). Draw and explain the distance–time graph assuming uniform motion between the stations.

Plot and interpret the distance-time graph for the train assuming that its motion between any two stations is uniform.
The equation for finding average speed is,
Average speed between station \(A\) to \(B\) \(=\) \(km\ h^{-1}\)
Average speed between station \(B\) to \(C\) \(=\) \(km\ h^{-1}\)
