A boatman rows 1 km in 5 minutes, along the stream and 6

A boatman rows 1 km in 5 minutes, along the stream and 6 km in 1 hour against the stream. The speed of the stream is

According to question ,

Rate downstream =	1	× 60 = 12 kmph
	5

∴ Speed of current =	1	(Rate downstream – Rate upstream) =	1	(12 - 6) kmph = 3 kmph
	2		2

Using the given formula :

Here, p =	1	× 60 = 10km/h , q = 6 km/hr
	5

Speed of Stream =		p - q
		2

Speed of Stream =		12 - 6		= 3km/hr
