Let the speed of boat in still water =B and speed of stream =S then B=16/3 km/h Let the time taken in downstream =x Then time in upstream =3x Speed of boat in Downstream =B+S Speed of boat in Upstream=B-S Now ATQ-. (B-S)3x =x(B+S) (B-S)/(B+S) =x/3x (B-S) =x … (1) (B+S) =3x … (2) So, Solving after (1) +(2) B=2x, S=x Now- 2x = 16/3 x= 16/6=8/3 x =S = 8/3 ×5/18 Speed of stream = (20/27) m/s
