A dinghy rower crossing the lake approached a distance-marking buoy on the route that said
"42" on the side facing him and "44" on the reverse. He thought the next buoy would show
that he was exactly at the midpoint of the route. However, the next buoy actually said "41"
facing him, and "45" behind.
Which of the following, if true, would explain the paradox above?
A) The second buoy’s numbers were reversed.
B) The buoys’ numbers are denominated in nautical miles instead of land miles.
C) The numbers facing him represent miles left to the end of the route, not miles from the beginning.
D) Between the two buoys the rower saw, one was missing.
E) Originally, the buoys had been built for use by sailboats, not rowboats.
how do we reason this?
