You can put this solution on YOUR website!
Let speed of the freight train be x, the speed of the express is x+20
\n" ); document.write( "Time taken express = freight
\n" ); document.write( "then, 600/(x+20) = 360/x
\n" ); document.write( "600x = 360x+ 20*360
\n" ); document.write( "240x = 20*360
\n" ); document.write( "x = 30
\n" ); document.write( "x+20 = 50
\n" ); document.write( "The rate of speed of express and freight train are 50 and 30 Kmph.
\n" ); document.write( " \n" ); document.write( "
