Blake and Ned work for home remodeling business they are putting the final touches on a home they renovated. working alone Blake
stiks02 [169]

Answer:

3.6 hours

Step-by-step explanation:

Blake can do work in hours = 9

Blake can do a part of work in 1 hour = \frac{1}{9}

Ned can paint the same room in six hours.

Ned can do a part of work in 1 hour = \frac{1}{6}

They can do a part of work together in 1 hour =  \frac{1}{9}+\frac{1}{6}

                                                                           =  \frac{5}{18}  

Now they can do \frac{5}{18}  part of work in hour = 1

So, they can do whole work in hours =  \frac{1}{\frac{5}{18}}

                                                             =  3.6

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