15 minutes of "mildly moderate" walking = 1500 steps
around 2 hrs.
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.
It will depend on how fast each steps I take.
around 10000 steps
i think 10000 steps it need to hatch
the egg hatches manaphy since manaphy and phione are different pokemon. it takes about 5000-10000 steps
for a adult its 10000 steps a day for a kids it depends on how old he is
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.
10000 hours
I think ALL eggs take 15000 steps to hatch.
