Raj went from Delhi to Chandigarh and return to Delhi on his motorbike. The odometer of that read 4200 km at the start of trip and 4460 km at the end of his trip. If Rajeev took 4 hour 20 minutes to complete his trip, then find the average velocity in kilometre per hour.

As we know that, the total distance covered,
S = final reading of odometer – initial reading of odometer
= (4460 – 4200) km = 260 km
Total displacement = 0 km
Total time taken, t = 4 h 20 m = 4.33 h
Average velocity = total displacement(d)/total time taken (t)
= 0/4.33 = 0
