Answer: d) 0.055 km east Explanation: Displacement is defined as the difference between the start point to the end point. Assuming that we started from point zero, the displacement will be the same as the distance traveled. The rule that relates velocity, time and distance is: velocity = distance / time we are given that: velocity = 0.11 km/hr time = 30 minutes = 0.5 hour Substitute with the givens in the above equation to get the distance as follows: 0.11 = distance / 0.5 distance = 0.11*0.5 = 0.055 km As for the direction, we are given that it is eastwards
