salt has to break down first
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
For salt water to boil faster than plain water, the salt concentration would have to be fairly high. In addition, the salt water would need to be a salt water solution before putting the pot on to heat because of the density of the water content itself.
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.

Salt (or anything dissolved into water) will increase the boiling point of water. It will take longer to come to a boil. Salt reduces the vapor pressure of the water and so requires a higher energy level to boil.
Plain water evaporate faster.
Raises the temperature at which the water boilsAdding salt does not make the water boil faster, but makes the water boil at a higher temperature than 100 degrees Celsius. This may allow you to cook food in that water faster than in plain boiling water.
A possible diagram could show two separate containers, one filled with plain water and the other with salt water, both being heated. Temperature measurements over time could be plotted on the diagram to show the rate of temperature increase for each type of water. This could help visualize and compare whether salt water boils faster than plain water.
Spaghetti will cook faster in salt water compared to plain water because the salt increases the boiling point of the water, allowing it to reach a higher temperature more quickly. This results in faster cooking times for the pasta.

salt water boiled first i had to do an experiment and salt water won
