It's about 50 times as fast as a Bull
In other words, the speed of a Bull is 0.02 times 0.2130 miles per second.
(for animals involved in the Running of the Bulls, a.k.a. Encierro, San Fermin, Pamplona, Spain) (herd average speed)
The herd of the annual Encierro in Pamplona, Spain runs at an average speed of 0.0041 miles per second. The Encierro is run annually from July 7th through July 14th and involves 42 bulls, 77 oxen, and an estimated 17,000 runners over the course of the event.
It's about one-one-hundredth as fast as a Meteor
In other words, 0.2130 miles per second is 0.0082 times the speed of a Meteor, and the speed of a Meteor is 120 times that amount.
(formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")
Small meteoroids enter the Earth's atmosphere at speeds between 6.90 miles per second and 45 miles per second, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 1.70 miles per second.
It's about 150 times as fast as a Crocodile
In other words, the speed of a Crocodile is 0.0077 times 0.2130 miles per second.
(American Crocodile, Crocodylus acutus) (swimming speed)
An American crocodile can reach speeds in the water of up to 0.0017 miles per second. On land, larger crocodiles can "gallop" when fleeing danger at speeds of up to 0.0035 miles per second.
It's about 200 times as fast as Michael Phelps
In other words, 0.2130 miles per second is 176.470 times the speed of Michael Phelps, and the speed of Michael Phelps is 0.0056667 times that amount.
(at the Beijing Olympics, 2008; 200 m freestyle) (a.k.a. Michael Fred Phelps) (swimmer; 1985-)
Setting a world record, Michael Phelps swam the 200 m freestyle in 1:42.96 for an average speed of 0.001207 miles per second. Phelps would go on to win nine gold medals individually in the 2008 Olympics - more than all but eight of the competing nations.
It's about 250 times as fast as Walking Pedestrians (in Manhattan)
In other words, the speed of Walking Pedestrians (in Manhattan) is 0.0038 times 0.2130 miles per second.
(Manhattan; average speed; 8,978 person-sample)
A 2006 Study by the New York City Department of City Planning found that pedestrians in that city walk at an average rate of 0.00081 miles per second. Pedestrians wearing headphones, the study went on to find, walk at a slightly faster 0.00088 miles per second
It's about one-three-hundredth as fast as a bolt of Lightning
In other words, 0.2130 miles per second is 0.0035 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 290 times that amount.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 60 miles per second when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about 700 times as fast as an Iceberg
In other words, the speed of an Iceberg is 0.001 times 0.2130 miles per second.
(a.k.a. Berg) (Newfoundland iceberg average)
Moved by ocean currents and wind, icebergs can drift at speeds of about 0.0003 miles per second. The largest iceberg ever recorded was a found near Baffin Island, Nunavut and was estimated to be nine billion metric tons.
