Downstream(D).
Upstream so(U).
D+U = 11.
D-U = 5.
2D = 16.
D = 16/2.
D = 8km/hr.
Upstream so(U).
D+U = 11.
D-U = 5.
2D = 16.
D = 16/2.
D = 8km/hr.

D=11 U=5.
(D+U)/2=x.
11+5/2=X.
16/2=X.
8=X (stream speed).
(D+U)/2=x.
11+5/2=X.
16/2=X.
8=X (stream speed).

X+Y=11,
X-Y=5,
X+Y+X-Y=11 + 5,
2X=16.
Then, X=8.
X-Y=5,
X+Y+X-Y=11 + 5,
2X=16.
Then, X=8.
