A group of college students is volunteering for Homes for the Community during their spring break. They are putting the finishing touches on a house they built. Working alone, Wade can paint a certain room in 6 hours. Rhonda can paint the same room in 3 hours. How long will it take them working together to paint the room? Round your answer to the nearest hundredth if necessary.

2 hours.

Step-by-step explanation:

From the question given,

Wade can do the work alone in 6 hours.

Rhonda can do the same work in 3 hours.

Next, we shall determine how much work is done by Wade and Rhonda in 1 hour each. This is illustrated below:

If Wade can do the work alone in 6 hours.

Then Wade can do 1/6 of the work in 1 hour.

If Rhonda can do the same work in 3 hours.

Then Rhonda can do 1/3 of the work in 1 hour.

Next, we shall determine the work done by Wade and Rhonda when they work together. This is illustrated below:

Wade's 1 hour work = 1/6

Rhonda's 1 hour work = 1/3

Therefore, work done by Wade and Rhonda together in 1 hour = 1/6 + 1/3 = 3/6 = 1/2

Since they completed 1/2 of the work in 1 hour, it means they will complete the work in 2 hours.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
