(D) Average velocity is defined as the total displacement divided by the total time taken.Displacement is the shortest distance between the initial and final positions.In this case,the man starts from his home and returns to his home after visiting the market.Since the initial position (home) and the final position (home) are the same,the total displacement is $0 \; km$.Therefore,Average velocity $= \frac{	ext{Total Displacement}}{	ext{Total Time}} = \frac{0 \; km}{	ext{Total Time}} = 0 \; m/s$.

$A$ man walks on a straight road from his home to a market $2.5 \; km$ away with a speed of $5 \; km \; h^{-1}$. Finding the market closed,he instantly turns and walks back home with a speed of $7.5 \; km \; h^{-1}$. What is the magnitude of average velocity in $m/s$?
