Solution

The correct option is B Average velocity = 0 kmph
Average speed = 80 kmph
Given, the displacement of the car = 0 km
(As the initial position is the same as the final position)

Initial odometer reading = 2200 km,
Final odometer reading = 3800 km.
the distance covered = 38002200=1600 km
Time taken = 20 hours

We know:
Average velocity=Total displacementTotal time =0
Average speed=Total distanceTotal time
=160020=80 kmph

the average velocity of the car is 0 kmph, and the average speed of the car is 80 kmph
