Whats the max and min speed the boat can obtain relative to the shore, and its direction relative to current?

A fishing boat with a maximum speed of 3 m/s relative to the water is in a river that is flowing at 2 m/s.

1. A simple vector equation The maximum speed is sailing with the current The minimum speed is sailing against the current. Max = 3 + 2 = 5m/s Min = 3 -2 = 1 m/s
2. With the current, the boat can travel at 5 m/s relative to the shore and against the current, the boat can travel at 1 m/s relative to the shore.
3. Boats don't measure their speeds in METERS per seconds... they measure speed in KNOTS... so you need to convert your question into a UNIVERSALLY USED unit of measure... meters per second won't cut it. Your kind of problem is one of the reasons circular slide rules were invented.
