I'm not sure what exactly you're asking, but the distance from the Earth's surface at the equator, through the two cores (the outer core and the inner core), to the center of the Earth is approximately 3963 miles.
about 6370km from the earths surface,convert now to feet

approximately 1.3 can fit in Jupiters core
120-300
From the Wikipedia: "The outer core of the Earth is a fluid layer about 2,300 km ... thick" - With current technology, it isn't possible to go that deep AT ALL.If you just want a calculation based on a hypothetical machine, assume some speed, and then divide the distance by the speed.
24,901.55
The core of the Earth, about 4,216 kilometers across and 2635 miles, is thought to be divided into an outer core of liquid iron and a nearly solid iron inner core about 1,500 miles in diameter.
only 180 miles long

To the outside earth`s core is 4600 miles
The Earth's diameter is 7926.28 miles at the equator and 7899.8 miles at the poles.
