Let the speed of stream be '2x' km/hr. So, speed of boat in still water = 1.5 X 2x = '3x' km/hr So, upstream speed of the boat = 3x - 2x = 'x' km/hr And downstream speed of the boat = 3x + 2x = '5x' km/hr ATQ, (135/5x) + (135/x) = 54 Or, (27/x) + (135/x) = 54 Or, (162/x) = 54 So, 'x' = (162/54) = 3 Speed of boat in still water = '3x' = 3 X 3 = 9 km/hr Therefore, required time = (180/9) = 20 hours
