A river has a steady speed of 0350 ms a student swims, Ask an Expert

Academics

A river has a steady speed of 0.350 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 1.50 m/s in still water, how long does the trip take (swimming up and down in the current)?

__________________ s

If the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.)
