20 chats

Explanation:

20 chats are active on the average.

Solution below:

Employees = 30

Average chat request per hour = 240

Average chat session = 5 minutes

Using Littles law:

5 minutes x (240chats per hour / 60 minutes per hour)

= 5 minutes x 4

= 20 chats

On the average 20 chats per session are active
