    Time it takes to swim across a river

    The vertical side was labeled with the speed that the river was carrying the water, and the horizontal was labeled with the speed that the man was swimming

    Time it takes to swim across a river

    I tried drawing a triangle and solving for the hypotenuse, proceeding by trying to use t=d/v. Where am I going wrong?

    Time it takes to swim across a river

    Well at first I imagined a man swimming across a river, then I imagined the current pulling him downwards, and so I made a triangle and tried to solve for the hypotenuse, proceeding by trying to use t=d/v, but then I realized that it shouldn't be a triangle at all because the problem states that...

    Calculating Velocities and Times in a River Current: Solving for t in terms of c

    I know that velocity is the change in the position of an object divided by the time, and the variables are t and c and it's asking to express t in terms of c, but what place does velocity have in this problem?

    What are the best resources for learning about physics homework?

    Completely new to these Forums, so I'm trying to learn as much as possible about it. Stumbled upon here through failed attempts on my physics homework. All help will be much appreciated, thanks!
