ATQ, Let the upstream speed and downstream speed of the boat be x km/h and y km/h, respectively. So according to question: 66/x + 165/y = 13 ………………. (i) Also, 55/x + 110/y = 9 ……….. (ii) Solving (i) and (ii), we get x = 11 and y = 22 So, the upstream speed and downstream speed of the boat are 11 km/h and 22 km/h, respectively. Speed of the boat in still water = (11 + 22)/2 = 16.5 km/h Speed of the stream = (22 – 11)/2 = 5.5 km/h So, the desired difference = 16.5 – 5.5 = 11 km/h
