Answer:
A large-scale bakery is laying out a new production process for its packaged bread, which it sells to several grocery chains. It takes 12 minutes to bake the bread. How large of an oven is required so that the company is able to produce 4200 units of bread per hour (measured in the number of units that can be baked simultaneously)?
the oven must be able to bake 840 units of bread simultaneously
= 4,200 units of bread per hour / (60/12 minutes) = 4,200 / 5 = 840
Consider the baggage check-in process of a small airline. Check-in data indicate that from 9 a.m. to 10 a.m., 240 passengers checked in. Moreover, based on counting the number of passengers waiting in line, airport management found that the average number of passengers waiting for check-in was 30. How long did the average passenger have to wait in line?
average inventory = flow rate x flow time
average inventory = 30 passengers waiting in line
flow rate = 240 passengers / 60 minutes (1 hour) = 4
flow time = average inventory / flow rate = 30 / 4 = 7.5 minutes
