Explanation / Answer

On Average the Customers arriving at a rate o f 55 per hour A= 55

The servicing time per patient S= 2 Minutes per patient, S= 60 MINUTES/ 2 MINUTES = 30 per hour

The Average time a patient spends on the Emergency Room = A/S(S-A) = 55/30(55-30) = 55/750 = 0.0733 Hours = 4.4 Minutes

The average number of patients examined by the dosctor = 60minutes/5minutes = 12 pateints per hour

The average number of patients admitted in the Emergency room = 10% of 55 = 5.5 per hour
