Answer:
3 hour 18 minutes or 3 hour
Explanation:
According to the given situation, the computation of time on average is shown below:-
The Average waiting time in the system
= [tex]\frac{1}{\mu} -\gamma[/tex]
Now we will put the values into the above formula to reach the time on average which is here below:-
[tex]= \frac{1}{20} - 1[/tex]
[tex]= \frac{1}{19}[/tex]
= 0.053 × 60 minutes
= 3 hours 18 minutes
We assume [tex]\gamma[/tex] is 1 hour
Therefore for computing the time on average we simply applied the above formula.
