1 If the average time between customer arrivals is 8 minutes

1.       If the average time between customer arrivals is 8 minutes, what is the hourly arrival rate?

7.5 customers

8.0 customers

8.5 customers

9.0 customers

Solution

A customer arrives in 8 minutes.

So, after every 8 minutes, one customer is served. So, in an hour, the arrival rate of customers

= 60 min / 8 min

= 7.5 customers per hour.

So, option A is correct.
