\n" ); document.write( "

Let the speed of the passenger train be S
\n" );
document.write( "Then the speed of the freight train = S - 20
\n" );
document.write( "We then get the following DISTANCE equation: 3S = (2 + 3)(S - 20)_____3S = 5S - 100
\n" );
document.write( "3S - 5S = - 100
\n" );
document.write( "S, or 
\n" );
document.write( "Speed of freight train:  \n" );
document.write( "

\n" );
