hey, I was reading my lecture notes and I'm stuck trying to understand this example.(adsbygoogle = window.adsbygoogle || []).push({});

A checkout operator can deal with 10 customers per hour. We assume it takes exactly 6 minutes to service each customer.

The shoppers arrive in groups of 10, every hour. (Average arrival rate of 10/hr)

Q1. How many people are in the queue on average?

A. 4.5

Q2. What's the average waiting time in the Queue?

4.5 * 6 = 27 minutes.

Could someone please explain how these answers are derived.

Thanks :)
