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.
