A man can row 8 km/hr in still water. If the river is running at 3 km/hr, it takes 3 hours more in upstream than to go downstream for the same distance. How far is the place?	Select the correct option
A) 32.5 km B) 25 km C) 27.5 km D) 22.5 km E) None of these
Explanation :   Let the speed downstream = x and speed updstream = y   Then   (x+y)/2=8   =&gt; x + y = 16 ---(Equation 1)   (x−y)/2=3   =&gt; x - y = 6 ---(Equation 2)   (Equation 1 + Equation 2) = &gt; 2x = 22   =&gt; x = 11 km/hr   (Equation 1 - Equation 2) = &gt; 2y = 10   =&gt;y = 5 km/hr   Time taken to travel upstream = Time taken to travel downstream + 3   Let distance be x km   Then   x/5 = (x/11) + 3   =&gt; 11x = 5x + 165   =&gt; 6x = 165   =&gt; 2x = 55   =&gt; x = 27.5. Answer : Option 27.5 km
