Answer:

You could crush or grind it into smaller pieces, stir the solution, or increase the temperature of the solution.

Explanation:

Crushing or grinding increases the surface area of the salt that is exposed to the molecules of water.

Stirring increases the speed at which the particles of salt come in contact with the water molecules.

Heating the solution also increases the speed at which the particles of salt come in contact with the water molecules.
