That depends a lot on the circumstances: mainly the shape of the water's container (the key part here is, how much surface is exposed), and the temperature. If you spill one liter of water on the floor, it might well evaporate within minutes in some cases. If you spill it on a hot metal plate, it might take seconds to evaporate.
Put 2 cups outside on a sunny day. One with salt water and one with regular water. Check on them every 5 minutes or just watch them. Then you time how long the salt water took to evaporate compared against how long it took the regular water to evaporate. Then you'll have your answer.
