Let the speed of the stream be ‘x’ km/hr Therefore, speed of the boat in still water = 8.5x km/hr Upstream speed of the boat = 8.5x – x = 7.5x km/hr Downstream speed of the boat = x + 8.5x = 9.5x km/hr According to the question, 9.5x – 7.5x = 22 => 2x = 22 => x = 11 Therefore, upstream speed of the boat = 7.5x = 82.5 km/hr Required time taken = 495/82.5 = 6 hours
