Answer:- 1

Explanation:-

Solution:

\begin{aligned} S   +   W   =   14 . . . . . . . . (i) \\ S - W   =    8 . . . . . . . . (ii) \\ -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  - \\ from equation (i) \&  (ii) \\ S  =  11 km/h \\ W  =  3 km/h \\ Speed of current  =  3 km/h \end{aligned}

$\eqalign{ & {\text{S + W = 14}}........{\text{(i)}} \cr & {\text{S }} - \,\,\,{\text{W = 8}}........{\text{(ii)}} \cr & {\text{ - - - - - - - - - - - - - - - - - - - - - - - - - }} \cr & {\text{from equation (i) \& (ii)}} \cr & {\text{S = 11 km/h}} \cr & {\text{W = 3 km/h}} \cr & {\text{Speed of current = 3 km/h}} \cr}$
