Answer:
4 minutes
Step-by-step explanation:
There are two hours from 11:30 a.m. to 1:30 p.m
The hourly rate of service is:
[tex]r=\frac{300}{2}=150\ customers/hour[/tex]
If the average number of customers in the system (n) is 10, the time that a customer spends in process is given by:
[tex]t=\frac{n}{r} =\frac{10}{150}=0.06667\ hours[/tex]
Converting it to minutes:
[tex]t= 0.066667\ hours*\frac{60\ minutes}{1\ hour}\\t=4\ minutes[/tex]
A customer spends, on average, 4 minutes in process.
