Rate it takes Maria to mow the lawn working alone = 1/24 lawn per minute
\n" ); document.write( "Rate it takes Bill to mow the lawn working alone = 1/40 lawn per minute
\n" ); document.write( "
\n" ); document.write( "Rate it takes both to mow the lawn working together:
\n" ); document.write( "
\n" ); document.write( "\"1%2F24+%2B+1%2F40\" = \"5%2F120+%2B+3%2F120\" = \"8%2F120\" = 1/15 lawn per minute
\n" ); document.write( "
\n" ); document.write( "Since they can mow 1/15 of the lawn per minute, it stands to reason it takes them 15 minutes to to mow the entire lawn.
\n" ); document.write( "
\n" );
