Examine this presentation and compare with your example, and try to solve.
\n" ); document.write( "Note carefully that your example uses equal distance in both directions. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "travel rates equal times different distances, involve wind\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Did it help? The channel has also another example of travel rates which may yet be helpful.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Some help with the data table, based on travel rates rule RT=D, and implied variable assignments:\r
