Question
A boat takes 1/12th time in moving a certain distance
downstream than upstream. The ratio of the speed of the boat in still water and that of the current isSolution
Let the speed of boat in still water = x km/hr, and Speed of current = y km/hr Rate downstream = (x + y) km/hr, and Rate upstream = (x – y) km/hr Distance = Speed × Time Øž (x - y) × 12t = (x + y) × t => 12x - 12y = x + y => 12x - x = 12y + y => 11x = 13y => x/y = 13/11 = 13 : 11
