Question

Find the average speed and average velocity if an object travel from A to B 100 km in 2 hours and come back to A in 1 hour.

Answer 1

average speed= distance/time
=100/3
=33.33km/hrs

average velocity=u+v/2

here initial position is 0,and final position is at 100km

so average velocity=100/2=50km/hr
