Answer :
           Distance = 10 km
           Speed = 4km / hr
           Time = ?
 we know that ,
     Speed = Distance Traveled / Time Taken
   Substituting the values , we get
         4  = 10 / T  (where T is the Time taken by Boat to Travel distance of 10 km)
  or T = 10 /4
    or T = 2.5 hours

Hope this helps you!!
