Question

A bus covers first 100 km at a uniform velocity of 50km/h and the next 100 km at 75km/h. Find the average velocity of the bus.

Answer 1

u=50km/hr

=50*5/18

=13.88m/s

v=75km/hr

=75*5/18

=20.83m/s

Average Velocity = u + v /2

=13.88+20.83/2

=17.355m/s

Answer 2

Answer:

17.36 m/s

Explanation:

u = 50 km/h

= 50×1000/3600 m/s

= 13.89 m/s

v = 75 km/h

= 75× 1000/3600 m/s

= 20.83 m/s

Average velocity = V+U/2

= 20.83 m/s +13.89 m/s /2

= 17.36 m/s
