Land Speed Record Broken: 0-6,400 in Six Seconds

JatTDB Re:The numbers don't add up! (362 comments)

Stop thinking about averages. It's accelerating the whole time, and the 6400mph number is the maximum speed. If it started that last 1.3s at a fairly low speed and only achieved the max towards the end, you'd still come out with an average speed for that segment in the range you mention.

A car that can go 0-60mph in 10s and use 200 feet of road in the process only averages 13mph in that 200 feet, but it's certainly travelling much faster than that at the end.
