A person travels along a straight road for half the distance with velocity v1 and the remaining half distance with velocity v2. The average velocity is given by
1
\(\frac{{{v_1}{v_2}}}{{2\left( {{v_1} + {v_2}} \right)}}\)
2
\(\frac{{{v_1}}}{{{v_2}}}\)
3
\(\frac{{{v_1} + {v_2}}}{2}\)
4
\(\frac{{2{v_1}{v_2}}}{{{v_1} + {v_2}}}\)
