A particle covers half of its total distance with speed v1 and the rest half distance with speed v2. Its average speed during the complete journey is

• v1v/ v1 + v2

• 2v1v2/v1 + v2

• 2v12v22 / v12 + v22

• v1 + v2 / 2

B.

2v1v2/v1 + v2

Velocity v = s / t

s = vt

The average speed of particle

Velocity v = s / t

s = vt

The average speed of particle
