    A particle moving with uniform acceleration along a straight line covers distances S1S_1 and S2S_2 in successive time intervals t1t_1 and t2t_2. Which equation correctly relates these quantities?

    A

    S_2t_1 - S_1t_2 = a(t_1+t_2)

    B

    S_2/t_2 - S_1/t_1 = a(t_1+t_2)/2

    C

    S_2t_1 + S_1t_2 = a(t_1+t_2)

    D

    S_2/t_1 - S_1/t_2 = a(t_1+t_2)/2
