dc.description.abstract We present a measurement of the average b-hadron lifetime t at the eqey collider LEP. Using hadronic Z decays b collected in the period from 1991 to 1994, two independent analyses have been performed. In the first one, the b-decay position is reconstructed as a secondary vertex of hadronic b-decay particles. The second analysis is an updated measurement of t using the impact parameter of leptons with high momentum and high transverse momentum. The combined result is τb=[1549±9(stat)±15(syst)]fs. In addition, we measure the average charged b-decay multiplicity 〈nb〉and the normalized average b-energy 〈xE〉b at LEP to be 〈nb〉=4.90±0.04(stat)±0.11(syst),〈xE〉b=0.709±0.004(stat+syst). en
