Let r = speed of boat in still water.
\n" ); document.write( "Let d = distance either direction.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Fundamental Rate*Time=Distance
\n" ); document.write( "Downstream, \"%28r%2B6%295=d\"
\n" ); document.write( "Upstream, \"%28r-6%298=d\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The distance is the same for both directions.
\n" ); document.write( "\"%28r%2B6%295=%28r-6%298\"
\n" ); document.write( "Solve for r.
\n" ); document.write( "
