Question
A goa can travel at a speed of 8 
in still water on a lake. In the flowing water of a stream, it can move at 
relative to the water in the stream. If the stream speed is 3, how fast can the boat move past a tree on the shore in travelling (i) upstream (ii) downstream?
and 
and 
- and
- and
and and and and The correct answer is: and
For upstream motion, km
=5
For downstream motion,
