A river has a steady speed of 0.482 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point.

(a) If the student can swim at a speed of 1.24 m/s in still water, how long does the trip take?

(b) How much time is required in still water for the same length swim?

s

(c) Intuitively, why does the swim take longer when there is a current?
