Incorrect Question 10 0/1 pts Patients arrive at an outpatient department (OPD) at the rate of 4 patients per hour. After arrival each patient is seen by a Nurse (NP) who spends 10 minutes with each patient to take vitals and determine which physician the patient must see. A fraction of patients are directed to a general practitioner (GP), who takes 15 minutes to serve a patient, and the remaining patients are directed to a specialist practitioner (SP), who takes 45 minutes to serve a patient. Patients leave the clinic after seeing a physician. If the number of patients arriving per hour remains 4, what that maximum fraction of patients that can be directed to specialist practitioner without decreasing hourly flow rate?
