Question
![**Topic: Swimming Against and With the Current**
A river has a steady speed of \( v_s \). A student swims upstream a distance \( d \) and back to the starting point.
**Problem a: Time to Swim Upstream**
If the student can swim at a speed of \( v \) in still water, how much time \( t_{\text{up}} \) does it take for the student to swim upstream a distance \( d \)? Express your answer in terms of \( d \), \( v \), and \( v_s \).
\[ t_{\text{up}} = \frac{d}{v - v_s} \]
*Note: There is an error indicated with an "x" next to the equation.*
**Problem b: Time to Swim Downstream**
Using the same variables, how much time \( t_{\text{down}} \) does it take to swim back downstream to the starting point?
\[ t_{\text{down}} = \frac{d}{v + v_s} \]
*Note: There is an error indicated with an "x" next to the equation.*
**Description:**
The image explains a scenario where a student swims in a river with a current. There are two parts: calculating the time to swim upstream against the current and downstream with the current. Equations for both parts are given, but both have a red "x" indicating a mistake. This might be a hint to review and correct or analyze what is incorrect.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb5f65923-b5e6-4be3-9be2-727b112c89ca%2F801fd181-f66a-4d43-b223-a176acb80306%2F7hh85e_processed.jpeg&w=3840&q=75)
