Jawaban:
Total distance traveled = 23 km
Total time taken = 28 min = 28/60 hr
(a) Average speed of the taxi=
Total time taken
Total distance traveled
=
(28/60)
23
= 49.29 km/h
(b) Distance between the hotel and the station = 10 km = Displacement of the car
Average velocity =
(28/60)
10
= 21.43 km/h
So, the two physical quantities (average speed and average velocity) are not equal.
