\n" ); document.write( "speeds are x mph and x+ 10 mph\r
\n" ); document.write( "\n" ); document.write( "1.5( x + x + 10) = 165\r
\n" ); document.write( "\n" ); document.write( "=> 3x + 15 = 165\r
\n" ); document.write( "\n" ); document.write( "=> 3x = 165-15 = 150\r
\n" ); document.write( "\n" ); document.write( "=> x = 150/3 = 50 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, 50 mph and 60 mph...
\n" ); document.write( "
