Answer 2

Lissette biked
`2(2)/(3)\ miles`

Explanation:

Let

x -----> the number of miles Shane biked

y -----> the number of miles Lissette biked

we know that

`x=3y-1` -----> equation A

`x=7` ----> equation B

Equate equation A and equation B and solve for y

`3y-1=7\\ 3y=7+1\\ 3y=8\\ y=(8)/(3)\ miles`

Convert to mixed number

`(8)/(3)\ miles=(6)/(3)+(2)/(3)=2(2)/(3)\ miles`
