Coverage of a specific distance by a man in stream (upstream and downstream) can be determined without any difficulties by using this distance covered by a person in upstream downstream formula. The man’s speed in still water, the stream speed flowing from one place to another and time consumed to reach upstream than downstream are the data necessary to perform calculation using this formula. The distance covered can be calculated in kilometre (km) units using this simple formula.

Where,

a = Speed in still water (km/hr)

b = Speed of stream (km/hr)

t = Time taken in upstream than downstream (hours)

This distance covered by a person in upstream downstream formula in this page requires only basic arithmetic operations to determine the distance.
