(a) Total distance travelled = 23 km Total time taken = 28 min = 28 / 60 h â?´ Average speed of the taxi = Total disttance travelled / Total time taken = 23 / (28/60) = 49.29 km/h (b) Distance between the hotel and the station = 10 km = Displacement of the car â?´ Average velocity = 10 / (28/60)...
