Call the distance from a to b \"+d+\" miles
\n" ); document.write( "If there were no current at all, the boat
\n" ); document.write( "would cover \"+d+\" in \"+t+=+d%2F7+\" hours
\n" ); document.write( "-----------
\n" ); document.write( "In \"+d%2F7+\" hours, the current would have moved
\n" ); document.write( "the boat downstream \"+2%28d%2F7%29+\"
\n" ); document.write( "-----------
\n" ); document.write( "The boat would be 2/7 of the distance a-b
\n" ); document.write( "from b downstream
\n" ); document.write( "
\n" );
