\n" ); document.write( "\n" ); document.write( "Let the first car travel x miles in the week\r
\n" ); document.write( "\n" ); document.write( "Average of first car = x/25 \r
\n" ); document.write( "\n" ); document.write( "The second car travesl 2025-x miles in that week\r
\n" ); document.write( "\n" ); document.write( "The average of second car = 2025-x / 35\r
\n" ); document.write( "\n" ); document.write( "x/25 + 2025-x / 35 = 65\r
\n" ); document.write( "\n" ); document.write( "35x+25*2025 -25x / 35*25* 65\r
