Q. No.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. \(\frac{4v}{3}\)
1. \(\frac{3v}{4}\)
2. \(\frac{v}{3}\)
3. \(\frac{2v}{3}\)
4. \(\frac{4v}{3}\)

| 1. | \(\frac{1}{v} = \frac{1}{v_1}+\frac{1}{v_2}\) | 2. | \(\frac{2}{v} = \frac{1}{v_1}+\frac{1}{v_2}\) |
| 3. | \(\frac{v}{2} = \frac{v_1+v_2}{2}\) | 4. | \(v = \sqrt{v_1v_2}\) |
