\n" ); document.write( "The calculation you performed indicates that when the number of hours is reduced by a factor of 24 the number of men required is also reduced by a factor of 24.

\n" ); document.write( "That of course goes against common sense. As the time decreases by some factor, the number of men required increases by that factor.

\n" ); document.write( "12 men times 24 hours = 288 man-hours
\n" ); document.write( "x men times 1 hour = 288 man-hours --> x = 288

\n" ); document.write( "or just...
\n" ); document.write( "12*24 = x*1
\n" ); document.write( "288 = x
\n" ); document.write( "
\n" );
