No, salt water does not boil faster than water with pepper. Adding salt or pepper to water may change its boiling point slightly, but the difference is not significant enough to affect the time it takes to boil.

Salt water boils more rapidly then unsalted water.
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
Salty water boils at a higher temperature than pure water does.
No, salt water boils slower than fresh water because the presence of salt increases the boiling point of the water. This means that salt water requires higher temperatures to reach the boiling point compared to fresh water.
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.
Water with salt will actually take longer than water without salt to evaporate. This is due to boiling point elevation. If you put a solute into water, it will make it more difficult to boil, and therefore will boil at a higher temperature. Since it takes longer for the salt water to boil, it will take longer for it to evaporate as well
