Question

A particle covers half of its total distance with speed v₁ and the rest half distance with speed v₂. Its average speed during the complete journey is

${{{v_1} + {v_2}} \over 2}$

${{{v_1}{v_2}} \over {{v_1} + {v_2}}}$

${{2{v_1}{v_2}} \over {{v_1} + {v_2}}}$

${{v_1^2v_2^2} \over {v_1^2 + v_2^2}}$
