If I'm not mistaken, it's not based on time, but steps, as in most of the game events related to that. I think it is 10000 steps.
So, to answer your question directly, how much time it takes to hatch an egg is however long it takes you to get 10000 steps built up. I recommend a bicycle because that still counts as steps and it's fast.
5,000.
A thousand!
Depending on the Pokemon, it could be anywhere from around 2000 steps to 10000 steps. Rarely, the steps could be around 20000, but very rarely. Most Pokemon hatch at around 5000, though.
It takes 10,496 steps for a Larvitar egg to hatch.

It takes about 500 steps, but it also depends on the size of the pokemon.
