A rare whale fossil was uncovered under layers of sediment. When the excavator took
measurements, she found the tail to be as long as its head plus a quarter of the length of the
body. When the archaeologist came in, he measured the length of the body. He found it to be
of the total length. They made arguments about how such a fish would swim in the water. To
make proper predictions they measured the head size, and found it to be 4 inches long. What is
the total length of this whale?
