Question

An express train moving from station A to B, covers half the distance with a uniform velocity of 5 m/s. The remaining half the distance is covered with a velocity of 10 m/s for half the time and 20 m/s for the other half time. Then, its average velocity is (m/s)

Answer 1

Answer:

i think so 11.67m/s

Explanation:

average velocity = u+v/2 but here 3 velocities so i done on my own so iasked is correct

Answer 2

Answer:

12.5km/s

Then, its average velocity in (m/s)
