Question

A train travell with a speed of 60km /hr^-1 from station a to station b and return with aspeed of 80 km/hr ^-1 from station b to

a.find the average speed and average velocity

Answer 1

Here A to B is a perticular distance

V1=60km/hr and V2=80km/hr

Then the average speed=2V1*V2/V1+V2

2*80*60/80+60=180km/hr

Here the particled returned back to the point so displacement=0

Average velocity= total dispacement/total time taken

=0/t=0
