Answer:
17.68 minutes
Step-by-step 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.
