Question

The speed-time graph of a particle moving along a fixed direction as shown in the figure. The distance traversed by the particle between t = 0 s to t = 10 s is

• A. 20 m
• B. 40 m
• C. 60 m
• D. 80 m

Answer 1

Answer: (C)

60 m

Answer 2

Distance = Area under speed – time graph over a given time interval.

$\therefore$Distance traversed by the particle between

t = 0s to t = 10 s will be = Area of $\Delta OAB$

$= \frac{1}{2} \times 10 \times 12$ 60 m
