    A body moves in a straight line for time t1t_1 with velocity v1v_1 and for time t2t_2 with velocity v2v_2 in the same direction. If the average velocity is equal to (2v1v2)/(v1+v2)(2v_1v_2)/(v_1+v_2), then the condition relating t1t_1 and t2t_2 is:

    A

    t1t2=v1v2\frac{t_1}{t_2} = \frac{v_1}{v_2}

    B

    t1t2=v2v1\frac{t_1}{t_2} = \frac{v_2}{v_1}

    C

    t1=t2t_1 = t_2

    D

    t1v1=t2v22t_1v_1 = t_2v_2^2
