Hi Helpipad7gen,
Sorry I don't know precisely how much time and data is needed for your update.
The article (link below) has information about the time and data requirements,
but doesn't give precise amounts.
If your iPhone, iPad or iPod touch won’t update
Says:
Eg: If there isn't enough space to download and install an update,
the software on your device will try to make space.
Eg: The time it takes to download the update varies,
according to the size of the update and your Internet speed.
