Sound is nominally 720 miles per hour. Rather leisurely IOW.
A perfect cable is C speed, 258 times faster. But cable (coaxial) actually
range in speeds between 66% of C for home usable cables, to around 98% of C
for 9" diameter high power broadcast stuff, C being 186,272 miles per
second in a vacuum. Thats 298,035.2 kilometers per second for the metric
folks here.
Just a tiny comment to the speed ratio: There is a missing factor
seconds/hour. Light is travelling in the magnitude of one million faster
than sound in air.
