Ariver flows with a speed of 0.600 m/s. a student first swims upriver 0.500 km, then turns around and returns to his starting point. the student swims at a constant speed of 1.20 m/s relative to the water. (a) how long does the round trip in the river take? (b) how long would a trip of the same length take in still water? (c) explain why it takes longer to swim in moving water, considering that it takes longer to swim upriver but shorter to swim downriver.
