10X+10(X+5)=850
\n" ); document.write( "10X+10X+50=850
\n" ); document.write( "20X=850-50
\n" ); document.write( "20X=800
\n" ); document.write( "X=800/20
\n" ); document.write( "X=40 MPH FOR THE SLOWER TRAIN.
\n" ); document.write( "40+5=45 MPH FOR THE FASTER TRAIN.
\n" ); document.write( "PROOF:
\n" ); document.write( "10*40+10*45=850
