If the speed of a boat in still water is 3 km/h and if its speed upstream is 1 km/h, find the speed of the stream.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2 km/h.
Upstream Speed = Speed in still water - Speed of stream
1 = 3 - Speed of stream
Speed of stream = 3-1 = 2 km/h
Hence, Speed of stream is 2km/h.
