Downstream speed of the boat = x + 1.25x = 2.25x km/hr For I: 2.25x = 810/18 => 2.25x = 45 => x = 20 Therefore, speed of boat in still water = 1.25x = 25 km/hr Therefore, I is false. For II: 2.25x = 810/12 => 2.25x = 67.5 => x = 30 Therefore, speed of boat in still water = 1.25x = 37.5 km/hr Therefore, II is true. For III: 2.25x = 810/18 => 2.25x = 45 => x = 20 Therefore, speed of the boat in still water = 1.25x = 25 km/hr Therefore, III is false.
