Consider the same urgent care center with $4$ doctors where the average arrival rate for each doctor is $24$ patients per hour and the

average service time of each patient is $2$ minutes. Both inter$-$arrival times and service times have a coefficient of variation equal to

one. But now,

the doctors are pooled so that a doctor can serve any patient. After pooling, how many minutes does a patient spend on average

in the urgent care center $($including the time waiting in line as well as the actual service$)?$ Round your answer to two decimal points.
