Yes dissolving salt in water is a physical change. The chemical structure was not changed, no chemical reaction took place, no precipitate formed and so on.
The best way to tell the difference between a chemical and physical change is the ability to change the substances back to the way they were.
Salt can be removed from water through evaporation of the water leaving both substances chemically the same before the salt was added.
However there is some debate upon this. Just go with whatever your teacher says.
