Data taken with an improved tracking system have been used to determine the average lifetime of B-hadrons, τB. A study of the pseudo decay length gave {Mathematical expression}. From the impact parameter distribution of high p ⊥ electrons and muons, values of {Mathematical expression} and {Mathematical expression} were obtained. Combining these results, allowing for correlations and adding statistical and systematic errors in quadrature, we obtain {Mathematical expression}
