Two cars are driven around a 10 kilometre track.
\n" ); document.write( "Both cars leave from the start line at the same time.\r
\n" ); document.write( "\n" ); document.write( "Car X travels at exactly 40km/h
\n" ); document.write( "Car Y travels at exactly 30km/h\r
\n" ); document.write( "\n" ); document.write( "How many minutes will it be before they pass the start line together?
\n" ); document.write( "-------------
\n" ); document.write( "Car X takes 15 minutes per lap.
\n" ); document.write( "Car Y takes 20 per lap.
\n" ); document.write( "The LCM (Least Common Multiple) is 300 minutes.
\n" ); document.write( "--> 300 minutes.
\n" ); document.write( "
\n" ); document.write( "
\n" );
