A river has a steady speed of vg. A student swims upstream a distance d and back to the starting point. (a) If the student can swim at a speed of v in still water, how much time t.n does it take the student to swim upstream a distance d? Express your answer in terms of d, v, and v tup = v+ v (b) Using the same variables, how much time tdown does it takes to swim back downstream to the starting point? d tdown = v+vs
