    1.In water ,the direction along the stream is called downstream and ,the direction against the stream is called upstream.

    2.If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr,then:
    speed downstream=(u+v)km/hr.
    speed upstream=(u-v)km/hr.

    3.If the speed downstream is a km/hr and the speed upstream is b km/hr,then :
    speed in still water=1/2(a+b)km/hr
    rate of stream=1/2(a-b)km/hr
