A coaxial cable lying over the peak of a roof is the same length on each
side.
It weighs one third of a pound per foot. On one end hangs an Extra
holding a
dipole, and on the other end a weight equal to the weight of the Extra.
The
dipole weighs two ounces per inch. The cable is as long (in feet) as the
age
of the Extra (in years), and the weight of the Extra (in ounces) is the
same as
the age of the Extra's mother. The combined age of the Extra and his
mother is
seventy years. One half of the weight of the Extra, plus the weight of
the
dipole, is one forth as much as the weight of the weight and the weight of
the
cable. The Extra's mother is half as old as the Extra will be when he is
three
times as old as his mother was when she she was half as old as the Extra
will
be when when he is as old as his mother will be when she is four times as
old
as the Extra was when he was twice as old as his mother was when she was
one
third as old as the Extra was when he was old as his mother was when she
was
three times as old as the Extra was when he was one fourth as old as he is
now.

How long is the dipole?

that can't be from the question pool... they are all multiple guess and you
didn't give me 4 answers with 3 stupid looking ones to throw out!
