3.6 hours

Step-by-step explanation:

Blake can do work in hours = 9

Blake can do a part of work in 1 hour = 1/9

Ned can paint the same room in six hours.

Ned can do a part of work in 1 hour = 1/6

They can do a part of work together in 1 hour =  1/9+1/6

                                                                          = 5/18  

Now they can do 5/18}  part of work in hour = 1

So, they can do whole work in hours =  1/5/18

                                                            =  3.6

Hence it will take 3.6 hours to paint the room if they work together.
