After Pooling Q1 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.
