Rate*Time=Output
\n" ); document.write( "I think you've got the gist of it.
\n" ); document.write( "\"36%2A5\" is the constant for output.
\n" ); document.write( "So any product of rate and time must equal \"36%2A5\"
\n" ); document.write( "\"48%2AT=36%2A5\"
\n" ); document.write( "\"T=%2836%2A5%29%2F48\"
\n" ); document.write( "\"T=%283%2A5%29%2F4\"
\n" ); document.write( "\"T=15%2F4\"
\n" ); document.write( "
\n" ); document.write( "
