- Boat B, because it is the one turning
- Boat A, because B is on its starboard side
- The faster boat, whichever it is
Mostra la risposta
Risposta: C. Boat A, because B is on its starboard side

- Stop its engine immediately
- Keep its course and speed
- Speed up to get past quickly
- Turn toward the other boat
