SortStack #1289 — 2029-12-19

By speed · Order from slowest to fastest.

1. A running spotted hyena 63 km/h

   Spotted hyenas are skilled hunters, not just scavengers, and live in matriarchal clans led by females.

2. A racing greyhound 76 km/h

   Greyhounds reach their top speed in just a few strides and spend much of a sprint completely airborne.

3. A top-fuel dragster 540 km/h

   A dragster covers a quarter mile in under four seconds, accelerating harder than a fighter jet off a carrier.

4. The speed of sound at sea level 1.2K km/h

   Sound travels faster in warm air than cold, so a thunderclap's timing shifts slightly with the weather.

5. A tank's sabot round 5.8K km/h

   A sabot round sheds a casing in flight, leaving a slim dart of dense metal that punches through armour.

6. The Earth orbiting the Sun 107K km/h

   We are all hurtling around the Sun fast enough to cross between two cities in a single second, yet we feel nothing.
