It sounds like they are including the effect of
\n" ); document.write( "the wind to arrive at their speeds.
\n" ); document.write( "Let $\"+d+\"$ = the one-way distance
\n" ); document.write( "Let $\"+t+\"$ = time in hrs for 1st leg
\n" ); document.write( " $\"+6+-+t+\"$ = time in hrs for 2nd leg
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "(1) $\"+d+=+235t+\"$
