Rahul walks

50\,\text{m}

north and then

30\,\text{m}

south in

40\,\text{s}

. Which option correctly compares the magnitudes of his average speed

(v_{\text{avg}})

and average velocity

(\bar v)

for the whole walk? (a)

v_{\text{avg}} = \bar v

(b)

v_{\text{avg}} < \bar v

(c)

v_{\text{avg}} > \bar v

(d) Both

v_{\text{avg}}

\;and\;

\bar v

are zero
