19.03790831 minutes to travel 6400 kilometers
Casio fx-100MS gives it right to the point.

Assuming you could keep the molton lava from filling the hole, and assuming you could shield yourself from heat, it would take a very long time to drift to the center if you let air into the hole.
Even at the surface of the earth, under a mere 1 atmosphere of pressure, terminal velocity of a human being is only 125 mph. As you approach the center, the atmospheric pressure will really increase. According to 1 calculator I found, even at 100 km below sea level, atmospheric pressure would be 88,700 times that at sea level. So, terminal velocity at that pressure would be about 7 feet per hour. Also, the force of gravity will decrease to zero as you approach the center. So by the time you reach the center you will hardly be moving at all.
If you did evacuate air out of the hole, you'd reach the center in 21 minutes, and you'd pop up on the other side of the world 21 minutes after that,

There's really not enough information to answer this question, since the distribution of mass in the planet's center isn't well known, which strongly affects the answer. For example, if the earth were a hollow shell, with all of its mass located in the crust, once you dropped below the surface you would simply stop accelerating, and you'd fall at constant velocity through the center of the sphere.

ummm it is impossible to dig a hole to the center of the earth. the implement that you were using would melt far before you got anywhere near there. Also, evien if you could dig the hole, a person would not survive the fall or the heat.

Yikes!
Assuming no air friction etc:
x = Vo*t + 1/2 a*t^2
Assuming Vo = 0
t = (2x/a)^1/2 where a ~9.8 m/sec^2 and x = 6400 km
t = 1140 sec or about 19 minutes at which point you'd be going a nice brisk 11 km per second!

You cannot fall and touch the center. Such a hole is not possible to dig.

He wouldn't ever touch the center, he would burn up first. The core is composed mostly of iron and is so hot that the outer core is molten.

21 minutes assuming no air friction

no! you will be cooked by the hot core. it is cooking down there.

that person won't survive, the person will burn before he gets there
