The Concept of Boats & Streams

The boat and stream concept is one of the most common topics based on which questions are asked in the various competitive exams conducted in the country.

The boat and stream questions are asked in the QA section of the Government exams and mostly the weightage of questions varies between 1-3 marks.

Downstream motion of a boat is its motion in the same direction as the flow of the Stream. Upstream motion is exactly the opposite.

There are two parameters in these problems.

1. Speed of the Stream (S): This is the speed with which the river flows.

2. Speed of the boat in still water (B): If the river is still, this is the speed at which the boat would be moving.

The effective speed of a boat in upstream = B – S

The effective speed of a boat in downstream = B + S
