Using salt

The time that it takes for an ice cube to melt is dependent on many factors including the size, shape, surrounding temperature, and pressure.
The addition of salt forms a solution which lowers the melting point of ice. This may have a slight effect on how fast it melts, but it would be mainly negligible. Salt is important because it lowers the melting temperature, allowing ice to melt below 32 F or 0 C.

Even using salt, it would depend on the room temperature. If you were in a room of 200ºF (you'd probably die in that kind of temperature, but this is just an example), even using salt, it would melt a lot faster than using salt in a room of 50ºF, and a lot slower than if the ice with salt on it was 10 feet from the sun. So, there is an infinite amount of time lengths that it would take an ice cube to melt with salt on it. Therefore, mathematically, the answer to this question is indeterminate.
There you go. I'm glad I could help. :)

Drop ice cube in a glass of salt water @ time it .

It is relative to the size of the ice cube.

I won't melt, no matter how much salt you add, if you keep if cold enough. Look up Fahrenheit, and how the zero point was set.

without salt its depending on the size and the room teperture that u have.

I'm going to guess 22 minutes
