A car travels 100 km east and then 100 km south. Finally, it comes back to the starting point by the south-east route. Throughout the journey the speed is constant at 60 kmh -1 . The average velocity for the whole journey if time taken is 3.3 hours is:

Question

Philoid · Accepted Answer

We know that, Velocity =

Now, Displacement = Final Position – Initial position

Since, the car comes back to its starting point, so, displacement = 0

Therefore, Velocity = = 0 kmh^-1

Hence, option C is correct
