Question

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. How many miles did Drew walk?

Answer 1

Drew walk 2 miles.

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
`x.`

As, given Maria walked twice as far as Drew.

So, Maria walked =
`2x.`

Justin walked = 3 miles.

Together they walked = 9 miles.

According to question:

`x+2x+3=9`

`3x+3=9`

Subtracting both sides by 3 we get:

`3x=6`

Dividing both sides by 3 we get:

`x=2.`

Therefore, Drew walk 2 miles.
