Total Distance = 120 m + 60 m = 180 m


Total Displacement = 120 m – 60 m = 60 m, towards east.


Time Taken = 5s + 1s= 6 s


Average speed = Distance / time taken 


                         = 180 m / 6 s 


                         = 30 m/s


Average velocity = Displacement / time taken 


                             = 60 m / 6 s 


                             = 10 m/s
