Question

Addison and wyatt whine a lot For every 3 minutes Wyatt whines, Addison whines 2 minutes. If they whine 45 minutes all together, for how long did Addison whine?

Answer 1

To solve this problem you must apply the proccedure shown below:

1. You have that Addison whines 2 minutes for every 3 minutes Wyatt whines. And they whine a total of 45 minutes. Therefore, you can make the following system of equations, where $x$ is the minutes that Wyatt whines and $y$ the minutes that Addison whines:

$\left \{ {{x=\frac{3}{2}y } \atop {x+y=45}} \right.$

2. You can solve it by the Method of subtitution:

$x+y=45$

$\frac{3}{2}y+y=45$

$\frac{5}{2}y=45$

$y=18$

3. Now, calculate $x$

$x+18=45$

$x=27$

Therefore, the answer is: Addison whined for 18 minutes.
