Train I x mph
\n" ); document.write( "Train II x+ 10 mph
\n" ); document.write( "..
\n" ); document.write( "They are moving away from each other
\n" ); document.write( "
\n" ); document.write( "So add up their speed.
\n" ); document.write( "
\n" ); document.write( "combined speed = x+ 1 x + 10
\n" ); document.write( "( 2 x + 10 )
\n" ); document.write( "Time = 4.5 hours
\n" ); document.write( "Distance = 405 miles
\n" ); document.write( "Distance = speed * time
\n" ); document.write( "( 2 x 10 )* 4.5 = 405
\n" ); document.write( "9.00 x + 45 = 405
\n" ); document.write( "9 x = 405 + -45
\n" ); document.write( "9 x = 360
\n" ); document.write( "/ 9
\n" ); document.write( "x= 40 mph
\n" ); document.write( "Train I = 40 mph
\n" ); document.write( "Train II 40 + 10 = 50 mph
