Question

A river has a steady speed of .650 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.45 m/s in still water, how long does the trip take? How much time is required in still water for the same length swim? A river has a steady speed of .650 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.45 m/s in still water, how long does the trip take? How much time is required in still water for the same length swim?

Explanation / Answer

upstream net speed is 0.650 m/s
downstream net is 2.1 m/s
t = d/v
up time + down time = total time
1000/0.650 + 1000/2.1 = 1538.46 + 476.190 = 2014.65 or 2015 s

still water
2000/1.45 = 1379.31 or 1380 s
