She would not so much be disagreeing with the lifeguard as unaware of the lifeguard's perspective. The extent to which these processes enable the lifeguard to approximate what is for her the unique least-time path is of course an empirical question. Lacking wings, the lifeguard is essentially confined to a two-dimensional surface. In the absence of external physical constraints, the path taken by the lifeguard is necessarily determined by her own internal processes and representations. Even if the lifeguard is an excellent swimmer, she can run across the sand more swiftly than she can swim through the water. The lifeguard on duty watches as the event unfolds and does nothing to help. So we each have a separate right to the plank, and based on that right, the lifeguard has a separate duty to each of us. If the lifeguard does communicate information about the tides, then there will be perfect agreement. Merely to say that the lifeguard "takes advantage of" this complex higher-order relation ignores the internal structure that must be approximately tuned to this relation within the lifeguard. But, of all these paths, the lifeguard wants to take the one that maximizes the probability of a favorable outcome, which (in this case) is the one that minimizes time.
