A river has a steady speed of 0.420 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 1.40 m/s in still water, how long does the trip take? (No Response) s (b) How much time is required in still water for the same length swim? (No Response) s (c) Intuitively, why does the swim take longer when there is a current? (No Response)

Expert Solution
Step 1
In upstream flow, the speed of the student swimmer is equal to the difference in the speed of the current and the speed of the student swimmer.
In downstream flow, the speed of the student swimmer is equal to the sum of the speed of the current and the speed of the student swimmer.
