The police start their patrolling jeep exactly at 12\u2019o clock but for 2 minutes they could not move the jeep due to some engine issues. Please answer:
\r\n (i) If the car is moving still why the line is running parallel to the x axis horizontally?
\r\n (ii) Please draw the first 2 minutes of the police jeep when it was not able to move. Draw the line on this graph.
