Hi,
Working together, paul and daniel can pick forty bushels of apples in 4.95 hrs.
 Had he done it alone it would have taken daniel 9 hrs. 
How long{{{highlight(x)}}} would it take paul to do it alone?
Question states*** PER hour Key
 1/9 + 1/x  = 1/4.95   |Multiplying thru by{{{9*4.95x}}} so as all denominators = 1
  4.95x + 9*4.95 = 9x    
          {{{9*4.95/ 4.05= x = 11hr}}}


 {{{1/9 + 1/11 = 20/99 = 1/4.95}}}
