How to Solve Boats and Streams Problems
Boats and streams problems are solved by adding the stream’s speed to the boat’s speed for downstream travel and subtracting it for upstream travel, then apply…
How to Solve Upstream and Downstream Speed Problems
Downstream speed (with the current) equals boat speed plus stream speed, while upstream speed (against the current) equals boat speed minus stream speed, so bo…
How to Find a Boat's Speed in Still Water
A boat's speed in still water is its own propulsion speed with no current acting on it, calculated as the average of its downstream and upstream speeds: still-…
How to Solve Boats and Streams (Relative Speed) Problems
In boats-and-streams problems, effective speed downstream is boat speed plus current speed, and effective speed upstream is boat speed minus current speed, bec…
How to Solve Boats Upstream Time-Ratio Problems
Upstream speed equals boat speed minus current speed, downstream speed equals boat speed plus current speed, and since distance is fixed, the ratio of upstream…
How to Solve Boats Round-Trip Time Problems
A round trip’s total time is the sum of the upstream leg time and the downstream leg time computed separately, total time = d/(b−c) + d/(b+c), which simplifies…
How to Solve Stream Current-Speed Problems
Current speed is found by isolating it algebraically from the two basic relations upstream speed = boat speed − current speed and downstream speed = boat speed…
