A boat can be rowed with the stream at 15 km/h and against the stream at 12 km/h.Find the speed of the stream.(with statements)

up stream speed =12 and down steam =15..Speed of steam 1/2(downspeed -up speed) =3/2

down Stream speed, a=15, up stream speed, B=12
speed of Stream =1/2(a-b)
1/2(15-12)=3/2
speed of Stream =1/2(a-b)
1/2(15-12)=3/2

Ok
ur welcome
mention not!!!!!
what
o gosh!
didn't you mention the formula above as 1/2(a+b) ?? then why have you answered the question as 1/2(a-b)
in your qustion. there has only to find out the speed of Stream that's way I comment speed of Stream forumlula..
why?what else is this formula used for?
to give in the problem down steam speed with the current and upstream speed with the current that's time we will follow 1/2(Downspeed -Upstream speed)

In boat with stream (x+y)=15km/h
against stream (x-y)=12km/h
subtracting both equations and we get
2y=3km/h
=1.5km/h
speed of streamer is 1.5km/h
HOPE ITS HELP YOU
