Formula and units
Ground speed = paddle + signed stream. Time = distance ÷ positive ground speed. In speed mode, required ground = distance ÷ target hours; required paddle = required ground − stream.
Scope
Use nonnegative distance and paddling speed, signed finite stream, and positive target hours in speed mode. Positive stream assists along the route; negative stream opposes it. This is constant-speed arithmetic, not a typical-speed estimate or navigation guide. No recommendations are supplied.
