To find the speed of the stream, we can follow these steps: ### Step 1: Define Variables Let the speed of the stream be \( V \) km/h. The speed of the boat in still water is given as 5 km/h. ### Step 2: Determine Speeds Upstream and Downstream - When rowing upstream (against the current), the effective speed of the boat is: \[ ...
