Jeff can weed the garden twice as fast as his sister Julia. Together they can weed the garden in 3 hours. How long would it take
Leona [35]
<h2>Hello!</h2>

The answer is:

The correct option is:

A) Jeff, 4.5 hours; Julia 9 hours.

<h2>Why?</h2>

To solve the problem, we need to write two equations using the given information.

So, writing the first equation we have:

We know that Jeff can weed the garden twice as fas as his sister Julia, so:

JeffRate=2JuliaRate

Also, from the statement we know that they can weed the garden in 3 hours, so, writing the second equation we have:

JeffRate+JuliaRate=\frac{1garden}{3hours}

Then, we need to substitute the first equation into the second equation in order to isolate Julia's rate, so, solving we have:

JeffRate+JuliaRate=\frac{1garden}{3hours}

2JuliaRate+JuliaRate=\frac{1garden}{3hours}

2JuliaRate+JuliaRate=\frac{1garden}{3hours}

3JuliaRate=\frac{1garden}{3hours}

JuliaRate=\frac{1garden}{3hours*3}=\frac{1garden}{9hours}

We have that Julia could weed the garden by herself in 9 hours.

So, calculating how long will it take to Jeff, we have:

JeffRate=2*JuliaRate\\\\JeffRate=2*\frac{1garden}{9hours}=\frac{2garden}{9hours}=\frac{1garden}{4.5hours}

We have that Jeff could weed the same garden by himself in 4.5 hours.

Hence, the correct option is:

A) Jeff, 4.5 hours; Julia 9 hours.

Have a nice day!
