It doesn't.
Salt raises the boiling point of water. So actually, adding salt to water makes that water boil more slowly. ( But it does reduce cooking time, because salted water that is boiling is hotter than unsalted water that is boiling.)

: Adding salt to water raises the temperature that the water boils at. The more salt you add, the higher the temperature. Adding 2 tablespoons of salt to 2 cups (473 milliliters) of water can raise the boiling point from 212 degrees Fahrenheit (100 degrees Celsius) by 5 degrees to 217° F (102.8° C).

Boiling the water will kill the bacteria salt isn't needed

I have never seen that happen. From a physics point of view the purer (non-salted) water should be the one that boils first since its boiling point is lower.

No, it definitely makes water boil slower. in spite of the undeniable fact that this will enhance the cooking temperature and so will reason meals boiled in salt water to cook dinner swifter. organic ideas will often have decrease boiling factors than mixtures.

it doesnt
adding salt, or any other solute to a solvent raises that solvent's vapor pressure, which in turn raises the boiling point,
the definition of the boiling point of a liquid is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure of its surroundings
this is why pressure cookers raise the boiling point of water (making cooking time shorter), and why at high altitudes the boiling point of water is lowered (making cooking time longer).

It doesn't. It merely allows the temperature to rsie above the normal (100C) boiling point of pure water.

because some of the water is absorbed by the salt causing a lesser density of water. And if there is a smaller amount of water level it will boil faster that a larger amount.

i dont know but i know it will kill any bacteria or stuff like that in the water
