A person travels along a straight road for half the distance with velocity ${v_1}$ and the remaining half distance with velocity ${v_2}$ The average velocity is given by
${v_1}{v_2}$
$\frac{{v_2^2}}{{v_1^2}}$
$\frac{{{v_1} + {v_2}}}{2}$
$\frac{{2{v_1}{v_2}}}{{{v_1} + {v_2}}}$
A person travels along a straight road for half the distance with velocity ${v_1}$ and the remaining half distance with velocity ${v_2}$ The average velocity is given by
As the total distance is divided into two equal parts therefore distance averaged speed $ = \frac{{2{v_1}{v_2}}}{{{v_1} + {v_2}}}$
