A motor lanuch takes 50 s travel 100 m upstream and 25 s to travel the same distance downstream . What is the speed of the current and the launch ?

Text Solution

AI Generated Solution

To solve the problem, we need to determine the speed of the motor launch (x) and the speed of the current (y). We can do this by using the information provided about the time taken to travel upstream and downstream. ### Step-by-Step Solution: 1. **Define Variables**: - Let the speed of the motor launch in still water be \( x \) m/s. - Let the speed of the current be \( y \) m/s. ...
