We propose a new method to extract {vert_bar}V{sub td}/V{sub ts}{vert_bar} from the ratio of the decay distributions dR/ds{equivalent_to}(dB/ds)[B{r_arrow}X{sub d}l{sup +}l{sup {minus}}]/(dB/ds)[B{r_arrow}X{sub s}l{sup +}l{sup {minus}}]. This ratio depends only on the KM ratio {vert_bar}V{sub td}/V{sub ts}{vert_bar} with 15{percent} theoretical uncertainties, if dilepton invariant mass-squared s is away from the peaks of the possible resonance states, J/{psi}, {psi}{sup {prime}}, etc. We also give a detailed {ital analytical and numerical} analysis on (dB/ds)[B{r_arrow}X{sub q}l{sup +}l{sup {minus}}](q=d,s) and dR/ds. {copyright} {ital 1997} {ital The American Physical Society}
