Question
A river has a steady speed of vs. A student swims upstream a distance d and back to the starting point.
(a) If the student can swim at a speed of v in still water, how much time tup does it take the student to swim upstream a distance d? Express your answer in terms of d, v, and vs.
(b) Using the same variables, how much time tdown does it takes to swim back downstream to the starting point?
(c) Sum the answers found in parts (a) and (b) and show that the time ta required for the whole trip can be written as
(Do this on paper. Your instructor may ask you to turn in this work.)
(d) How much time tb does the trip take in still water?
| tup | = |

(b) Using the same variables, how much time tdown does it takes to swim back downstream to the starting point?
| tdown | = |
