Freight Train x 240 miles
\n" ); document.write( "Passenger Train x+ 18 330 miles
\n" ); document.write( "
\n" ); document.write( "t=d/r
\n" ); document.write( "240 / x = 330 / ( x+ + 18 )
\n" ); document.write( "Cross multiply
\n" ); document.write( "240 ( x + 18 ) = 330 * x
\n" ); document.write( "240 x + 4320 = 330 x
\n" ); document.write( "330 x -240 x = 4320
\n" ); document.write( "90 x = 4320
\n" ); document.write( "/ 90
\n" ); document.write( "x = 48 Freight Train mph
\n" ); document.write( " 66 Passenger Train mph
\n" ); document.write( "
