Jordan can build a birdhouse in 2 hours. If it takes her sister 3 hours to build a birdhouse, how long will it take them to buil
miskamm [114]
To find the total work of two people at different speeds, we need to find a common speed limit to both.

In this case, Jordan can build a birdhouse in 2 hours so her speed is 1/2 birdhouse per hour.

For the sister, it takes 3 hours to build a birdhouse so her speed is 1/3 birdhouse per hour.

To find what they can do in one hour: \frac{1}{3} + \frac {1}{2} = \frac{2}{6} + \frac{3}{6} = \frac{5}{6}

To find how long does it take to build a birdhouse: \frac{ \frac{5}{6}}{1} = \frac{1}{x}

Set the denominators equal: \frac{\frac{5}{6}x}{x} = \frac{1}{x}

Remove the denominators and solve: \frac{5x}{6} = 1

Once again set the denominators equal: \frac{5x}{6} = \frac{6}{6}

Remove the denominators and solve for x: 5x = 6  \\ \\ x = \frac{6}{5}

6/5 hours is equal to 72 minutes.
