Algebra II - Word Problem
posted by John .
A convenience store clerk can wait on 6 customers per minute. If customers arrive at an average rate of x people per minute, the time T spent in line is:
T=1/6-x, where 0<x<6
Find the waiting time if an average of 4.75 people arrive each minute.
T = 1/(6-x) = 1/(6-4.75) = 0.8 min.=48s.
