Think of the slower train as standing still

\n" ); document.write( "of their speeds
\n" ); document.write( "Let $\"+t+\"$ = time in hrs
\n" ); document.write( " $\"+440+=+%28+50+%2B+60+%29%2At+\"$
\n" ); document.write( " $\"+440+=+110t+\"$
\n" ); document.write( " $\"+t+=+4+\"$ hrs
\n" ); document.write( "1 PM + 4 = 5 PM is when they meet\r
