The crews of two eight-man sculls decide to race one another on a river of width \(D\) that flows at uniform velocity \(V_{0}\). The crew of scull A rows downstream a distance \(D\) and then back upstream, while the crew of scull B rows to a point on the opposite shore directly across from the starting point, and then back to the starting point. They begin simultaneously, and each crew rows at the same speed \(V\) relative to the water, with \(V>V_{0}\). Who wins the race, and by how much time?
