It depends a lot on your location. In the central latitudes with temperate climates, the depth may be only fifty or sixty feet. To find that same temperature in the higher latitudes you may have to travel through hundreds of feet of permafrost. (You will quickly pass through the zone of thaw/freeze in the upper permafrost to a layer of stable, sub freezing temperatures that remain constant).
In the lower latitudes you may have more stable year round temperatures at a shallow depth than in other latitudes, but to get to a 'global temperature' you would have to go deeper. I have heard, (many years ago) that this temperature should be about 52 degrees F.
You don't have to go too deep to get into the zones of rising temperature. Some deep mines, (shallow in terms of the thickness of the crust), have temperatures well over 100 degrees F.
Except for ancient permafrost areas I would expect to find a stable temperature at less than a half mile in most locations.

A few hundred ft it will be 52 deg. F. but as u drill deeper it will come up about 1 deg every hundred ft.

It's not far down. All of the caverns and caves around where I live stay about 50f all of the time.
