picturing a circular track makes things easier\r

\n" ); document.write( "\n" ); document.write( "the slow car goes 360º in 120 sec or 3° per sec\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the fast car goes 360° in 90 sec or 4° per sec\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "every second the cars are traveling, the fast car gains 1°
\n" ); document.write( "__ when the fast car has gained 360° (in 360 sec) the cars will pass again\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the cars pass every 360 sec or 6 min
