ATQ,
Let speed of boat in still water = ‘x’ km/hr And, speed of stream = ‘y’ km/hr ATQ, (x + y) = 22 ------- (I) And (x – y) = 14 -------- (II) By adding equation (I) and equation (II), we get 2x = 22 + 14 = 36 So, x = 18 so, speed of the boat in still water = 18 km/hr Required time = (162/18) = 9 hours
