Question

The speed-time graph of a particle moving along a fixed direction as shown in the figure. The distance transversed 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

The correct option is C 60 m

Since the upward slope is increasing curve $\frac{12}{5}$ and of the decreasing curve is $-\frac{12}{5}$. This gives the rate of change

So distance traveled is $2\times \frac{1}{2}\times (5\times 12)=60m$
