Straight distance between a hotel and a railway station is 10 km , but circular route is followed by a taxi covering 23 km in 28 min . What is the average speed and magnitude of average velocity? Are they equal?

Given in the question, Total Displacement = 10 km Total Distance = 23 km Total time = 28 60 h a Average speed = total distance total time = 23 28 60 = 49 . 3 km h - 1 b Average velocity = total displacement total time = 10 28 60 = 21 . 4 km h - 1 So, the average speed and average velocity is 49 . 3 km h - 1 , 21 . 4 km h - 1 and they are not equal.
