The actual charge carriers only go at about 30 MPH.

How fast does current flow ?
Already 6 Pages in one  week.

On average, that is.  Typical instantious speeds for electrons in metals are > 1000km/s !

In fact 30mph is a going to rapidly heat most metals, a few mm/s is common for drift
velocities in everyday wiring.

Electromagnetic waves propagate in vacuum at a maximum speed of 299,792,458 meters per second . For a 12-gauge copper wire carrying a 10-ampere DC current, the speed of electric current (average electron drift velocity) is about 80 centimeters per hour or about 0.0002 meters per second.

So for 1 week = 6 pages = 13.44km = turtle
