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.
  
Distances of Stations \(B\) and \(C\) from \(A\) and times of arrival and departure of the train
 
Station
Distance from \(A\) (\(km\))
Time of arrival (\(hours\))
Time of departure(\(hours\))
\(A\)
0
08:00
08:15
\(B\)
120
11:15
11:30
\(C\)

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 \(C\) \(=\)  \(km\ h^{-1}\)
