# Question: You are in a fast powerboat that is capable of

You are in a fast powerboat that is capable of a sustained steady speed of 20.0 m/s in still water. On a swift, straight section of a river you travel parallel to the bank of the river. You note that you take 15.0 s to go between two trees on the riverbank that are 400 m apart.

(a) (1) Are you traveling with the current, (2) are you traveling against the current, or (3) is there no current?

(b) If there is a current [reasoned in part (a)], determine its speed.
