Straight distance between a hotel and a ...

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

Text Solution

Verified by Experts

(a) Average speed= `("Total path length")/("Total time")`
`=(28)/((28//60)) = 49.3 kmh^(-1)`
(b) Average velocity= `("Displacement")/("Time")`
`= ("Shortest distance")/("Time") = (10)/(28// 60) = 21. 4 km//h`
(c ) Both are Not equal
