Easy
Which of the following graph can represent the distance time relation of an object?
Explanation
Explanation
Distance (total path covered) can never decrease with time - it must stay constant (during rest) or keep increasing. Only the graph that rises, has a flat/plateau portion (object at rest), and then rises again correctly represents this; a graph that decreases or dips is not physically valid for distance.
PRO TIP
Re-check your working by substituting the answer back into the original question.
