Helping here for #2, and you should try to work through #1 yourself.\r

\n" ); document.write( "\n" ); document.write( "One man rate is r.
\n" ); document.write( "The first sentence gives \"20r%2A24=1\", for the 1 job to be done.
\n" ); document.write( "The second sentence uses an unknown amount of time, t, after which men are added (4 of them) to finish the job in 3 days. This work was split into two parts, this way:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight_green%2824r%2At%2B%2824%2B4%29r%2A3=1%29\".
\n" ); document.write( "If all of this is well understood, then you can continue. The question asks for the value of t. The value for rate r will come from the equation from the first sentence.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "System of equations if this is more comfortable to see,
\n" ); document.write( "\"system%2820r%2A24=1%2C24rt%2B28r%2A3=1%29\"
\n" ); document.write( "
\n" );
