Consider the following diagram of a fast-food restaurant drive-through with three stops for each car following the path described by arrows in the diagram below. The time required to complete the work at each of these workstations is also listed here:

a. What is the maximum rate at which this restaurant can successfully serve arriv- ing cars with this product layout?

b. What is the efficiency implied by this design?

c. The employee who works at the first window, where the car's payment is pro- cessed, has just left the restaurant due to a family emergency. To keep operating, the restaurant has closed the first window and the employee at the second window is now doing the work required at both windows, processing payments and assem- bling and providing the meal to each of the cars. Now, due to this change, what is the maximum rate at which this restaurant can successfully serve arriving cars?
