Answer: 21

Explanation:

From the question, we are told that CodeDesk Inc matches programmers with freelance jobs and that it has 35 employees who staff its online chat room and also receives, on average, 250 chat requests per hour, and that the average chat session takes 5 minutes to complete.

To get the number of chat sessions that are active will be:

= (5 minutes * 250) / 60 minutes

= 20.83

= 21 approximately

It should be noted that 60 minutes makes 1 hour which was the reason the values were divided by 60
