passenger train270 mph
freight train210 mph
difference60 mph
\r
\n" ); document.write( "\n" ); document.write( "to build up this difference they had to ride for 60/12 = 5 hours and therefore
\n" ); document.write( "the passenger train's speed = 270 / 5 = 54 mph
\n" ); document.write( "the freight train's speed = 210 / 5 = 42 mph

\n" ); document.write( "and the difference in speed = 54 - 42 > 12 mph\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
