A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 1 hour to row to a place and come back, how far is the place?
2.4 km
2.5 km
3 km
3.6 km

• 2.4 kms
  
  upstream speed = 5-1= 4 kmph
  downstream speed = 5-1= 4 kmph
  
  If x is the distance in one direction, then
  
  x/4+x/6 =1
  
  solving it , we get
  x= 2.4 kms
