Answer: Probably 0.33km/hr south is the net velocity
Step-by-step explanation:
Speed= Distance/ Time
Speed in North = 5km/3hrs=1.67km/hr
Speed in South= 2/1hrs=2.00km/hr
Since north and south are in opposite directions, and taking north as the +ve y, we get 1.67-2.00= -0.33km/hr, (-ve represents south direction).
