1.	Figure. gives the x-t plot of a particle in one-dimensional motion. Three different equal intervals of time are shown. In which interval is the average speed greatest, and in which is it the least ? Give the sign of average velocity for each interval.
Answer» SOLUTION :Greatest in 3, least in 2, `UPSILON gt 0` in 1 and 2, `upsilon lt 0` in 3.
