x = slower car
\n" ); document.write( "x + 30 = faster car
\n" ); document.write( "-------------------
\n" ); document.write( "(x+30)(4) + (x)(4) = 400\r
\n" ); document.write( "\n" ); document.write( "4x + 120 + 4x = 400\r
\n" ); document.write( "\n" ); document.write( "8x + 120 = 400\r
\n" ); document.write( "\n" ); document.write( "8x = 280\r
\n" ); document.write( "\n" ); document.write( "x = 35
\n" ); document.write( "------------------\r
\n" ); document.write( "\n" ); document.write( "35 mph (slower car)\r
\n" ); document.write( "\n" ); document.write( "35 + 30 = 65 mph (faster car)\r
\n" ); document.write( "
