Let n be the speed of the car. Then the plane would be n+366. So:
\n" ); document.write( "2040/n+366=210/n
\n" ); document.write( "2040n=210n+76860
\n" ); document.write( "1830n=76860
\n" ); document.write( "n=42
\n" ); document.write( "The car goes 42 mph; the plane goes 408 mph.
\n" ); document.write( "☺☺☺☺
\n" ); document.write( "
\n" );
