Question

From the displacement-time graph of a cyclist given in the figure, find the time after which he reaches the starting point.

• A. $0s$ and $3s$
• B. $3s$ and $5s$
• C. $5s$ and $7s$
• D. $7s$ and $13s$

Answer 1

Answer: (D)

$7s$ and $13s$

In the graph, there are two such points, E and H.

Time taken to reach point E is $7s$ and time taken to reach point H is $13s$.
