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` minutes . What is (a) the average speed of the taxi, (b) the magnitude of average velocity ? Are the two equal ?

Answer

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