it would melt the ice
No, because the data does not show how quickly the ice would have melted without the salt.
Salt
The relationship between salt and ice temperature is that adding salt to ice lowers the temperature at which the ice melts. This is because salt disrupts the normal freezing process of water, causing the ice to melt at a lower temperature than it would without salt.
Cat litter can provide traction on ice, but it won't melt the ice like salt does. Salt is more effective at melting ice and preventing refreezing. If traction is your main concern, cat litter can be a good alternative to salt.
Salt makes the ice colder, and the the ice would melt faster.
Salt would melt the ice cube faster because if you have noticed, people put down salt to melt the ice.
All over the ice is when they need to melt the ice. So they would get alot of salt and pour it all over the ground or road.
no
Salted ice does not stay longer. Salted ice melts sooner than ice alone because the mixture of salt and water lowers the freezing point of water. So the salt-ice mixture will melt at temperatures where pure ice would freeze. The only way that a salt-ice mixture would stay longer is if the temperature is so low that it has reached the freezing point of the salt-ice mixture.
Instantly, the ice is already melted. If the ice weren't melted, it would depend on what salt was used and the temperature of the salt and the ice. Certain salts, like magnesium chloride, melt ice much faster and at a lower temperature than table salt. If the ice is really cold it won't melt, regardless of what salt is used.

Hypothesis: Sprinkle Salt on ice would melt the ice. Null-Hypothesis: Sprinkle Salt do ice do not melt the ice. Theory behind hypothesis: (explain what any why you believe the salt do or interact to melt the ice like if it exert heat from solution) Hypothesis is just write the sentence describe what would you believe in the result and what might be the cause of what is going on. You then design experiment base on your hypothesis.
