\n" );
document.write( "Jeff takes 5hrs longer to build a fence than it takes Bill.
\n" );
document.write( "Letting x and (x+5) represent Bill's and Jeff's times respectively\r

\n" );
document.write( "    Yes!!
\n" );
document.write( "Multiplying thru with 6x(x+5) so as all denominators= 1
\n" );
document.write( " 6x + 6(x+5) = x(x+5)
\n" );
document.write( "   12x +30= x^2 + 5x
\n" );
document.write( "    x^2 - 7x - 30

\n" );
document.write( "(x-10)(x+3)= 0
\n" );
document.write( "   x = 10 , x = -3  Throwing out x = -3
\n" );
document.write( "   x = 10hr is Bill's time and Jeff's is 15hr
\n" );
document.write( "  1/10 +1/15 = 25/150 = 1/6 \n" );
