Total displacement  =  10 Km

Total time taken in hours  :

                                      =\ \frac{28}{60}\ hr

Avg. velocity    :            

                                      =\ \frac{10}{\frac{28}{60}}\ hr      

                                     =\ 21.43\ Km/h

It can be clearly seen that avg. speed and avg. velocity is not the same.
