उत्तर
Analysing the graph carefully, we observe that
- He started his journey at 5:30 AM and end at 6 PM.
- Total duration of journey was 12:30 h.
- His forward journey is of duration 8:30 h and return journey is of duration 4 h. Forward journey was of longer duration.
- He did not move from 6:30 AM to 9:30 AM and 10 AM to 1 PM. So, he did not move for 6 h.
- He have the fastest speed at 1 PM.
