A quick-service restaurant has a single drive-through lane with one worker at the window. It is assumed that the worker can process an order every 3 minutes on average and that the processing (service) times are exponentially distributed. Customers arrive at the drive-through at the rate of 15 per hour. a. The worker at the drive-thru is busy ????? of time. (Enter your response rounded to two decimal places.) b. The average number of cars waiting at the drive-thru is...
1) A fast-food franchise is considering opening a drive-up window food service operation. Assume that customer arrivals follow a Poisson distribution ( interarrival times follow an exponential distribution), with a mean arrival rate of 24 cars per hour, and that service times follow an exponential probability distribution. Arriving customers place orders at an intercom station at the back of the parking lot and then drive up to the service window to pay for and receive their order. The following four...

7. The Canara Bank drive-thru teller window can serve a customer at an average of 4 minutes per customer. Service time has a negative exponential distribution. Customers arrive in their cars at a rate (Poisson distributed) of 12 per hour and form a single waiting line: a. Determine the average waiting time, the average queue length, and the probability that there is no customer in the system. b. If Canara Bank decides to open a second drive-thru teller window with...
Gionino's Pizzeria is considering opening a drive-through window for customer pickups. It is estimated that at peak times (5-9pm), customers will arrive at a rate of 10.3 per hour. The clerk who will staff the window can serve customers at the rate of 1 every 4 minutes. For the peak times, what is the average waiting time in line (in minutes)? Give your answer to 2 decimal places and do NOT list minutes. For example, answer like 3.24
