Bill Youngdahl has been collecting data at the TU student grill. He has found that students arrive at the grill at a rate of 50 per hour and service time takes an average of 2 minutes (exponential distribution for both arriving time and service time). There are 2 servers, who can work on only 1 order at a time. (Fill out number with three digits after the decimal) What is the utilization rate? What is the average time a student is waiting in line for a burger? mins. What is the average number of students in the system? Suppose a third server is added and the 3 servers act independently, with each taking an average of 2 minutes. What would be the average time a student is waiting in line for a burger? mins
