10Q. A man can row at 5 kmph in still water. If the velocity of current is 1 kmph & it takes him 1 hour to row to a place and come back, how far is the place?

a.) 2.5 km
b.) 3.6 km
c.) 2.4 km
d.) 3 km

• c) 2.4 km
  
  Let the distance of place=x km
  Downstream speed=5+1=6 kmph
  Upstream speed=5-1=4 kmph
  Total time taken = x/6 + x/4 = 1
  5x/12 = 1
  x = 12/5 = 2.4 km.
