A passenger arriving in a new town wishes to go from the station to a hotel located 10 km away on a straight road from the station . A dishonest cabman takes him along a circuitous path 23 km long and reaches the hotel in 28 min . What is (a) the average speed of the taxt , (b) the magnitude of average velocity ? Are the two equal ?

(a) `49.3kmh^(-1)`; (b) `21.4kmh^(-1)`. No , the average speed equals average velocity magnitude only for a straight path.
