Rewritten the way I see it:
: A platform is X feet below ground level.
: Joel is standing on it.
: Joel is five and half feet in height.
: His head is Y feet above ground level.
: The well is 6X feet deep.
: When Joel stood on the bottom of the well his head was 5Y feet below ground level
: How deep is the well?
Equation is easy: 6X = 5Y + 11/2 ; X = (10Y + 11) / 2
Also, both X and Y are < 11/2
If Y = 1/2, then X = 8 : too high
If Y = 0, then X = 11/2 !
SO: his damn head is below ground level...
So there's something wrong somewhere...
Maybe someone else can see what I did wrong.
