The approx. of 300,000 km/s or 186,000 miles/second are both quite close (exact speed is pointless until you need it for math at that level).
This is the fastest speed attainable in Eintsein's known universe - often called the "cosmic speed-limit," etc...
It's a truly mindblowing speed, and no particle of matter can travel at it's exact speed - but reaching 99.9999% of it is totally fine with our understanding of physics.
