Question

Consider the baggage check-in process of a small airline. Check-in data indicate that from 8 a.m. to 9:30 a.m., 360 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 30.

Required:
How long did the average passenger have to wait in line?

Answer 1

`Average = 7.5\ mins`

Explanation:

Given

`Time = 90\ mins` i.e. 8am to 9:30am

`Total\ Passengers = 360`

`Average\ Passengers= 30`

Required

Determine the average waiting time

The average waiting time is calculated as:

`Average = (Average \ Passengers)/(Total\ Passengers) * Time`

`Average = (30)/(360) * 90\ mins`

`Average = (30* 90\ mins)/(360)`

`Average = (2700\ mins)/(360)`

`Average = 7.5\ mins`

Hence, the average waiting time is 7.5 minutes
