Algebra II  Word Problem
posted by John on .
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/(6x), where 0<x<6
Find the waiting time if an average of 4.75 people arrive each minute.

I'm guessing it's 48 seconds, but not sure... Thanks!
