Think of the train at the station as standing still
\n" ); document.write( "and the disabled train is moving at the sum of their speeds
\n" ); document.write( "The disabled train has to travel 168 miles to get
\n" ); document.write( "to the station.
\n" ); document.write( "Let $\"+t+\"$ = the time in hours to get to the station
\n" ); document.write( "------------------
\n" ); document.write( " $\"+168+=+%28+32+%2B+80+%29%2At+\"$
\n" ); document.write( " $\"+168+=+112t+\"$
\n" ); document.write( " $\"+t+=+168%2F112+\"$
\n" ); document.write( " $\"+t+=+1.5+\"$
\n" ); document.write( "They will meet 1.5 hrs after 4 PM, or 5:30 PM
\n" ); document.write( " \n" ); document.write( "

\n" );
