The velocity versus time plot of a particle is shown in the figure, for a time interval of 40 s. The total distance travelled by the particle and the average velocity during this period are, respectively
______.

Show answer and solution
Answer: (c)
- The graph has four triangles, each of base and height : area each.
- Distance = sum of magnitudes
- Displacement = , so average velocity
- So the answer is (c) 100 m and zero.
