Hailey ran 12 km. this is 3 times farther than raul. how far did raul run?

12÷3=4. As a result, Raul runs 4 miles. Hope it help!

To find out how far Raul ran, we need to find our system of equations.
I will rewrite the question entirely. While I do that, I will translate in parenthesis the equation.

Hailey (H) ran (=) 12 km (12).
This is (H=) 3 times farther than Raul (3R).

Now, let's write what's only in parenthesis.

H = 12
H = 3R.

Since H = 12, substitute 12 for H.

12 = 3R is now our remaining question.

To find what R is, we need to take not that R is being multiplied by 3. To get R by itself (solve), we need to get rid of the 3.
One way to get rid of the 3 is to divide by 3.
The other way is to multiply by 1/3.
Remember, what you do to one side of the equation, you must do to the other side as well.
We'll make this simple, divide both sides by 3.
12 / 3 = 4.
3R / 3 = R

R = 4.

Your answer is:

Raul ran 4km.

I hope this helps!
