You can put this solution on YOUR website!
Put everything into a table of data.
\n" ); document.write( "RT=D is the travel rates rule relating R rate, T time, and D distance.\r
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "              RATE         TIME       DISTANCE\r\n" );
document.write( "A to B         s                       50\r\n" );
document.write( "B to C         r            t             40\r\n" );
document.write( "TOTAL                      \r\n" );
document.write( "

\n" ); document.write( "\n" ); document.write( "Some cell values are not yet known but are filled using variables as shown in the table.
