Boats and Streams Introduction

Boats & Streams
  1. DownStream : In water, the direction along the stream is called Downstream.
  2. UpStream : In water, the direction against the stream is called UpStream.
  3. 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) kmph

    Speed upstream = ( u - v) kmph
  4. If the speed downstream is $x$ km/hr and the speed of upstream is $y$ km/hr, then
    Speed in still water = $ {\cfrac{1}{ 2}  \times{(x+y)} }$ kmph

    Rate of Stream = $ {\cfrac{1}{ 2}  \times{(x - y)} } $ kmph
