Answer:
The car stops at a distance from the starting point because the portion shows a constant function away from the starting point.
Explanation:
For this case, the first thing you should keep in mind is the following definition: 
 d = v * t 
 Where, 
 d: distance 
 v: speed 
 t: time 
 For the portion of the chart labeled J we have: 
 The time increases 
 The distance is the same 
 We have then that the speed is zero. 
 Therefore, the car is stopped at a distance far from the starting point.
