Let n be Jessie's speed on her way to her parents. Then her speed back home would be n-9. So:
\n" ); document.write( "60/n + 60/n-9=3
\n" ); document.write( "60(n-9)+60n=3nē-27n
\n" ); document.write( "3nē-147n+540=0
\n" ); document.write( "nē-49n+180=0
\n" ); document.write( "(n-45)(n-4)=0
\n" ); document.write( "n=45 or 4
\n" ); document.write( "☺☺☺☺ \n" ); document.write( "
\n" );
