Un barco pequeño sale de un puerto y se mueve a 36 km/h en línea recta a 30º al noroeste durante 40 min. Luego de eso se detiene, pero aparece una pequeña corriente que mueve el barco a 5 km/h hacia el oeste. La tripulación del barco se entera de la corriente 3 horas después de que empezó a actuar, en ese momento deciden volver al puerto con la misma rapidez de 25 km/h y viajando en línea recta
