Austin and Dale earn money painting fences over the summer. Working alone, Austin takes twice as many hours to paint a fence as Dale. Working together, the two of them can paint a fence in 6 hours. How many hours would it take each of them working alone?

Required equation:

Together they can paint the same room in 2.25 hours or 2 hours 15 minutes.

Step-by-step explanation:

It is given that Dale Horton can paint a certain room in 3 hours.

One hour woks of Dale Horton = 1/3

Kathy Garcia can paint the same room in 9 hours.

One hour woks of Kathy Garcia = 1/9

Let together they can paint the same room in t hours.

One hour woks of both = 1/t

After reciprocal we get

1 hour = 60 minutes.

0.25 hour = 15 minutes.

Therefore, together they can paint the same room in 2.25 hours or 2 hours 15 minutes.
