Question 403901

let one piece be {{{x}}} and another one {{{y}}}


{{{240in =x+y}}}

since one piece is three times the length of the other, we have

{{{x=3y}}}..substitute in {{{240in=x+y}}} and find {{{y}}}

{{{240in=3y+y}}}

{{{240in=4y}}}

{{{240in/4=y}}}

{{{60in=y}}}


now find {{{x}}}

{{{x=3y}}}

{{{x=3*60in}}}

{{{x=180in}}}


the lengths of the pieces: 60in  and 180in
