A vehicle travels half the distance L with speed \(V_1\) and the other half with speed \(V_2\), then its average speed is
1. \(\frac{V_1+V_2}{2} \)
2. \(\frac{2 V_1+V_2}{V_1+V_2} \)
3. \(\frac{2 V_1 V_2}{V_1+V_2} \)
4. \(\frac{L\left(V_1+V_2\right)}{V_1 V_2}\)
1. \(\frac{V_1+V_2}{2} \)
2. \(\frac{2 V_1+V_2}{V_1+V_2} \)
3. \(\frac{2 V_1 V_2}{V_1+V_2} \)
4. \(\frac{L\left(V_1+V_2\right)}{V_1 V_2}\)
