Let the speed of the stream be 'x' km/hr So, speed of boat in still water = x X 4 = '4x' km/hr Distance between 'Y' and 'X' = (150/2) = 75 km/hr ATQ, (150/5x) + (75/3x) = 11 Or, (30/x) + (25/x) = 11 Or, (55/x) = 11 So, 'x' = 5 So, upstream speed of boat = '3x' = 3 X 5 = 15 km/hr Therefore, required time = (180/15) = 12 hours
