Question

A boy goes to a market 2 km far from his house in 30 min. He comes back from market to his house in 15 min. Find his average velocity.

Answer 1

Answer:

Average Velocity = Total Displacement / Total time taken.

Here, displacement will be zero, as boy went to market and again covered the same distance while coming and hence,now is at its initial position.

  So, Average Velocity = (0/ 45) km/min

                                        = (0/ 45) 1000/ 60 m/s

                                        = 0 m/s

Hope it helps you a lot.
