Answer:

[tex]Average = 7.5\ mins[/tex]

Step-by-step explanation:

[tex]Average\ Passengers= 30[/tex]

Required

Determine the average waiting time

The average waiting time is calculated as:

[tex]Average = \frac{Average \ Passengers}{Total\ Passengers} * Time[/tex]

[tex]Average = \frac{30}{360} * 90\ mins[/tex]

[tex]Average = \frac{30* 90\ mins}{360}[/tex]

[tex]Average = \frac{2700\ mins}{360}[/tex]

[tex]Average = 7.5\ mins[/tex]

Hence, the average waiting time is 7.5 minutes
