Question

a body takes 2 hours to move from point a to point B and 3 hours to come back the distance between a and b is 200 km find the average speed and average velocity

Answer 1

average velocity = distance / Time
= 200 / 2
= 100 km / hour

Answer 2

average speed =(200+200)÷(3+2)=400÷5=80km/h
average velocity =0 becaus e there is no displacement
