Consider the baggage check-in process of a small airline. Check-in data indicates that from 9am to 10am, 190 passengers checked in. Moreover, based on counting the number of passengers waiting in line, airport management found that the average number of passengers waiting for check-in was 56. Required:
How long did the average passenger have to wait in line?

17.68 minutes

Explanation:i

In order to calculate the average time passenger had to wait in line, we would first divide the average number of passengers check-in in with the passengers checked in from 9 am to 10 am (which was the highest number of check-ins of the day). Then we would multiply that number by 60 minutes. As shown below:

First,

= 56 average number of passengers checked-in / 190 passengers checked-in from 9 to 10 am

= 0.2947

Then

= 0.2947 x 60 minutes

= 17.68 minutes

Hence, 17.68 minutes did the average passenger wait in line.
