Answer:
Drew walk 2 miles.
Step-by-step explanation:
Given:
Maria,Drew,and Justin all took part in a walk-a-thon.
Together, they walked 9 miles. Justin walked 3 miles.
Maria walked twice as far as Drew.
Now, to find the miles Drew walk.
Let the miles Drew walk be [tex]x.[/tex]
As, given Maria walked twice as far as Drew.
So, Maria walked = [tex]2x.[/tex]
Justin walked = 3 miles.
Together they walked = 9 miles.
According to question:
[tex]x+2x+3=9[/tex]
[tex]3x+3=9[/tex]
Subtracting both sides by 3 we get:
[tex]3x=6[/tex]
Dividing both sides by 3 we get:
[tex]x=2.[/tex]
Therefore, Drew walk 2 miles.
