Dear studnent,

Current due to movement of sodium ions=I_{Na}=neAv_{Na}
Current due to movement of cholride ions=I_{Cl}=neAv_{Cl}
The two currents will be in the same direction since ions with opposite charges will move in opposite directions.

Hence total current flowing through the salt water=neA(v_{Na}+v_{Cl})
