It won't.
Let's say you have two cups of water; one cup is warm water, the other is cold water.
If you mix them, the final temperature of the water will be higher than the cold temp water was, but lower than the high temp water was.
And here's the thing: how you mix them is irrelevent. The results that you get if you pour the cold water into the hot are the same as the results that you get if you pour the hot water into the cold.
You might think that cold water cools off hot water faster because of your experiences with it, and here's why: when you normally use cold water to cool off hot water, the cold water is a lot colder than the hot water, because the water is usually coming out of a refrigerator or a faucet.
When you try to heat up cold water with warm water, the temperature difference between the cold and the warm usually isn't as large as the temperature difference between, say, a hot drink and ice water.
It's the temperature difference that matters. So, when you control the temperature difference, you find that it doesn't matter whether you put warm water in cold, or cold water in warm.

This should simplify your ?. First hot and cold are not opposites.Cold is without heat. think of heat as something that is added to. such as sugar too Kool/Aid. Now think that temperature is aways trying to equalize. A glass of cold water ( room temperature) and a glass of hot water out of the tap. sit side by side on a table' come back the next day. Both will be the same temperature. Hope this help.

You have some pretty good answers here. To clarify about hot water freezing faster than cold water, it won't. The hotter something is relative to its surroundings, all else equal, the more quickly it will lose heat. However, it won't "catch-up" to something which is already colder. So cold water always turns into ice earlier than hotter water.

hot water does NOT freeze faster than hot water. this myth was created because the hot water would melt the ice off of the coils.

for the same reason hot water freezes faster than cold water

Heat is transferred from warmer bodies to cooler bodies.
