Dear G Somaiah


7567-1896_7662_untitled.JPG

he reaches at the apposite end  of the rever then his horizontal component of speed must be equal to the velocty of the river

  vertical componen of velocit =5cos30 = 5√3 /2 km/h

 now time teken to cross the river = 1/√3  hr

so 1/√3 = d /5√3 /2

   d=5/2 km
