Jims plane speed = x
\n" ); document.write( "John's speed = 3x\r
\n" ); document.write( "\n" ); document.write( "Distance = 3000\r
\n" ); document.write( "\n" ); document.write( "\"%283000%2Fx%29-%283000%2F3x%29=10%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "LCD = 3x
\n" ); document.write( "\"%289000-3000%29%2F3x=10\"\r
\n" ); document.write( "\n" ); document.write( "6000=30x\r
\n" ); document.write( "\n" ); document.write( "x=200\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Speeds are 200 & 600 mph
\n" ); document.write( "
\n" );
