Distance, Displacement & Average Speed

A vehicle runs on a straight road of length 'L'. It travels half the distance with speed V and the remaining distance with speed $\frac{V}{3}$ . Its average speed is

Show answer and solution

Answer: (c)

For equal distances, $v_{avg} = \frac{2v_1 v_2}{v_1 + v_2}$ .
$v_{avg} = \frac{2V(V/3)}{V + V/3} = \frac{2V^2/3}{4V/3}$
So the answer is (c) $\frac{V}{2}$ .
