A boat goes 30 km upstream and 44 km ...

A boat goes 30 km upstream and 44 km downstream in 10 hours. In 13 hours, it can go 40 km upstream and 55 km downstream. Determine the speed of the stream and that of the boat in still water.

Text Solution

AI Generated Solution

To solve the problem, we need to determine the speed of the boat in still water (let's denote it as \( x \) km/h) and the speed of the stream (denote it as \( y \) km/h). ### Step-by-Step Solution: 1. **Define Variables:** - Let \( x \) = speed of the boat in still water (in km/h) - Let \( y \) = speed of the stream (in km/h) ...
