उत्तर
The starting point is where displacement = 0 m.
Looking at the graph:
The cyclist starts at point A (0 m at 0 s).
He returns to 0 m at point E at 7 s.
Again, he crosses 0 m at point H at 13 s.
The cyclist reaches the starting point (displacement = 0) at 7 seconds and 13 seconds.
So the first time he returns to the starting point is 7 seconds later.
