Due to a new business building built nearby, the customer
arriving at the cafeteria at a busy lunch hour was expected to more
than double to 297 customers per hour. To deal with the increased
demand, management has decided to open another checkout lane.
Workers were also provided with a faster POS machine, which will
cut down their processing time to about 17 seconds per customer.
What would be the service rate in hours (i.e., how many customers,
on average, can a server serve per hour)? Round your answer to the
nearest fourth decimal point. What is the system utilization? What
is the probability that a customer will arrive at the checkup
counter without having to wait at all? What would be the average
number of customers waiting in line? How many seconds will a
customer, on average, be waiting in line before reaching the front
of the line?
