A car travels 100 km east and then 100 km south. Finally, it comes back to the starting point by the shortest route. Throughout the journey, the speed is constant at 60 `kmh^(-1)` The average velocity for the whole of the journey is

A

60 `kmh^(-1)`

B

90 `kmh^(-1)`

C

0 `kmh^(-1)`

D

180 `kmh^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
