Question

During the two hours of the morning rush from 8 a.m. to 10 a.m., 100 customers per hour arrive at the coffee shop. The coffee shop has a capacity of 80 customers per hour. How long does the customer arriving at 10 a.m. have to wait to be served? 2 hours 1 hour 0.5 hour 0.25 hour

Answer 1

Time to serve the customer arriving at 10 a.m. = T × (Demand/Capacity - 1)

2 * (100/80 - 1) = 0.5

The customer arriving at 10 a.m. would have to wait 0.5 hours to be served.
