First freezes the pure water !
SALT I froze deployment of two types of missiles.

If you're trying to set up an experiment, the manipulated variables would be salt and sugar, and varying ratios of salt to water or sugar to water. Say you wanted to find out how fast water froze if it had sugar in it, and wanted to compare it to how quickly it froze with salt. Your controls would be the amount of water, the type of container, and the temperature of the freezer. You could pour 18 plastic cups of water, 6 plain water (the control), 6 with salt and 6 with sugar. You could also vary the amount of sugar or salt in the water (say, .5% to 2.5%, with an increase of .5% in each cup).

First of all, if the water is frozen, then you can't put an ice cube into it. Secondly, if you put an ice cube in liquid then froze it then it would become part of the liquid that froze.
The density of water with 50 grams of salt in it will be slightly higher than the density of pure water. The exact value will depend on the amount of water used, but in general, adding salt to water increases its density due to the presence of the dissolved salt molecules.
Water, but the difference is infinitesimal.
salt water boiled first i had to do an experiment and salt water won
The salt water gets warmer faster then the ice water, because salt water is in the sun and the salt water is heated by the sun.
