Round trip time of 110 meters in a river is 16 min. the velocity of stream is 3m/min. what is the velocity of the person in the still water?

• ans 8
  let speed of boat be x.hence upstream=x-3 and downstream=x+3..so we have
  55/x+3 + 55/x-3 = 16...solving we get x=8

• Distance travelled :110mts
  Time taken :16min
  
  In one min Distance travelled is :110/16=6.875
  
  This 6.875 is not in still water hence actual velocity is (6.875+0r-3)

• Distance travelled :110 metrs
  Time:16 min
  
  In one min Distance travelled is :110/16=6.875
  This 6.875 is not in still water.
  
  hence actual velocity is (9.875 or 3.875)i.e. + or - 3
