How fast can electricity travel in 10000 miles?

Electricity travels at the speed of light in a vacuum, which is approximately 186,282 miles per second. However, in conductors like copper wires, the speed is slower, typically around two-thirds of that speed, depending on the medium. Therefore, in an ideal situation, electricity could theoretically cover 10,000 miles in about 0.053 seconds in a vacuum, but in practical applications, it would take longer due to the limitations of the medium used.
