Let the downstream speed of the boat and speed of the boat in still water be 13x km/hr and 12x km/hr, respectively Therefore, speed of the stream = downstream speed - speed of boat in still water Or, speed of stream = 13x - 12x = 'x' km/hr And, upstream speed of the boat = 12x - x = 11x km/hr Or, 11x = 44 Or, 'x' = 4 So, downstream speed of the boat = 13x = 13 X 4 = 52 km/hr Required time = 208 ÷ 52 = 4 hours
