9. Complete Activity 7.9 (Page 80).
The times of arrival and departure of a train at three stations A, B and C and the distance of stations B and C from station A are given in Table 7.4.
Plot and interpret the distance-time graph for the train assuming that its motion between any two stations is uniform.
Answer:
The distance-time graph for the train is shown below:
The train stops at each station (A, B and C) for 15 minutes.
We can tell from the graph that:
Velocity of train while travelling from station A to B = velocity of train while travelling from station B to C.
Velocity of train while travelling from station A to B = 120 km/3 hrs = 40 km hr-1.
Velocity of train while travelling from station B to C = (180 – 120) km/1.5 hrs = 40 km hr-1.
