\n" ); document.write( "\n" ); document.write( "Nine employees working at the same rate require 15 days to complete a task. Which formula indicates how long it would take to do the same work if there were 3 additional employees each capable of working twice as fast as each of the original 9 employees?\r
\n" ); document.write( "\n" ); document.write( "It seems like a rate of work problem, but the solution can be reached much easier by dividing 9 x 5 - total work to be done - by 9 + 3 x 2 - total number of \"slower\" employees: 9x5/[9+(3x2)]. \r

9*15=135 man days
\n" ); document.write( "(9+ (3*2))*x=135
\n" ); document.write( "not only are there more workers but the new workers work faster.
\n" ); document.write( "15x=135
\n" ); document.write( "x=135/15
\n" ); document.write( "x=9 days
\n" ); document.write( "
