Answer:

45 minutes

Step-by-step explanation:

Assume task completed in total x hours

$\frac{x}{10} + \frac{3}{8} + \frac{3}{12} = 1 \\ 12x + 45 + 30 = 120 \\ 12x = 45 \\ x = \frac{15}{4} = 3 \frac{3}{4}$

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.
