1. 3v/4 2. v/3 3. 2v/3 4. 4v/3

Answer: 4. 4v/3 Average speed = total distance / total time. Let the total distance be 2s . t₁=s/v , t₂=s/2v , total time =3s/2v . v_avg=2s/3s/2v=4v/3 . The answer is 4v/3 .

A vehicle travels half the distance with speed v and the remaining distance with speed 2v. Its average speed is:

1. \(\frac{3v}{4}\)

2. \(\frac{v}{3}\)

3. \(\frac{2v}{3}\)

4. \(\frac{4v}{3}\)

Answer: 4. \(\frac{4v}{3}\)

Average speed = total distance / total time. Let the total distance be \(2s\).

\(t_1=\dfrac{s}{v}\), \(t_2=\dfrac{s}{2v}\), total time \(=\dfrac{3s}{2v}\).

\(v_{avg}=\dfrac{2s}{3s/2v}=\dfrac{4v}{3}\). The answer is \(4v/3\).
