well , in both of them - Ice water and boiling water - when it want to get to room's temperature , there is no change of material stat (I mean from Solid state to Liquid state , or gas to liquid ) so , it is a linear equation .
assume that where you are , the temprature of the boiling water is 100 degree of centigrad , and the temprature of Ice water is 0 degree of centigrad . so if we assume that the temprature of the room is normally 25 , so the Ice water will get faster to the room's temp .
but in 50 , it takes a same time for both of them (boiling water and ice water) to become 50 degrees.

The previous two answers are incorrect, or at least incomplete. Boiling water is 212-70=140 degrees from room temperature, ice-cold water is 70-32=38 degrees from room temp. Given the fact that the specific heat capacity is the same for both, the boiling water will take longer to reach room temperature. If the hot water is allowed to give off steam, that will accelerate the process slightly, but it will still take longer than the cold water.

Boiling water, with no additives, is 212 degrees Fahrenheit.
Ice cold water (not frozen) is just above 32 degrees Fahrenheit.
Room temperature is somewhere around 70 degrees Fahrenheit.
The ice cold water only has about 38 degrees to go, while the boiling water has to cool by about 142 degrees.
The ice cold water will reach temperature first.

I am thinking the ice cold water will take longer to get to room temperature.

The rate of heat flow is dependant on temperature difference.
If you assume room t is 20C, the ice water has 20C to go, the hot water has 80C to go.
The hot water initially loses heat faster, but when it gets down to 20C to go (40) it loses heat at the same rate as the ice water gains heat when the ice water has 20C to go. (0C)
So from 20C away from room T, the hot and cold water take the same time to reach room T.
Add the time the hot takes to change the extra 60 degrees and the hot takes longer.

ice water because it has to change states

Depends on what part of the world your room's in.

Water boils at 100F. Freezes at 0F. Room Temp is 32F.
