Can Bernoulli’s equation be used to describe the flow of water through a rapid in a river? Explain.

A river is flowing due east with a speed 3m/s. Swimmer can swim in still water at a speed of 4 m//s (shown in the figure) If he wants to start from pont A on south bank and reach opposite point B on north bank. What will be his resultant speed?
