How fast is 55 kilometers per hour?

Sort Order:
Closest first | Highest first | Lowest first

It's about three-tenths as fast as a Skydiver (belly-to-earth).
In other words, 55 kilometers per hour is 0.290 times the speed of a Skydiver (belly-to-earth), and the speed of a Skydiver (belly-to-earth) is 3.40 times that amount.
(Belly-to-Earth orientation, average conditions, terminal velocity)
A belly-to-Earth oriented skydiver's terminal velocity is about 190 kph. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 60 seconds.
It's about three-tenths as fast as a Tornado.
In other words, 55 kilometers per hour is 0.2767240 times the speed of a Tornado, and the speed of a Tornado is 3.6137090 times that amount.
(EF2) (wind speed range average)
According to the Enhanced Fujita scale implemented by the US National Oceanographic and Atmospheric Administration, a "significant" tornado has an Enhanced Funjita scale classification of EF2 and is characterized by wind gust speeds between 177.02784 kph and 220.480128 kph. The largest recorded tornado — an F4 event occurring in Nebraska in May, 2004 — was almost 4.02 km (2.5 mi) across.
It's about one-fifth as fast as a Skydiver (headfirst).
In other words, 55 kilometers per hour is 0.210 times the speed of a Skydiver (headfirst), and the speed of a Skydiver (headfirst) is 4.80 times that amount.
(Head-to-Earth orientation or standing, average conditions, terminal velocity)
A head-to-Earth or standing-oriented skydiver's terminal velocity assuming average conditions is about 260 kph. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 46 seconds.
It's about one-fifth as fast as a Helicopter.
In other words, 55 kilometers per hour is 0.1940 times the speed of a Helicopter, and the speed of a Helicopter is 5.150 times that amount.
(for AH-64A Apache, a.k.a. Hughes Model 77) (maximum cruise speed)
The AH-64 helicopter, one of the primary helicopters used by the United States Army, flies at a top cruise speed of 284 kph. The AH-64 is the primary military helicopter of several nations including the United States, the United Kingdom, Israel, Japan, and the Netherlands.
It's about five-and-a-half times as fast as a Crocodile.
In other words, the speed of a Crocodile is 0.180 times 55 kilometers per hour.
(American Crocodile, Crocodylus acutus) (swimming speed)
An American crocodile can reach speeds in the water of up to 10 kph. On land, larger crocodiles can "gallop" when fleeing danger at speeds of up to 20 kph.
It's about one-fifth as fast as an Arrow (archery).
In other words, 55 kilometers per hour is 0.17040 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 5.8690 times that amount.
(250 g arrow fired from 60#/28" bow)
A 250 gram arrow will reach speeds of approximately 322.8 kph when fired from a 60-lb, 28-inch draw bow . Archeological evidence from the Ahrensburg valley near Hamburg, Germany indicates that arrows have been used since at least 11 to 12,000 years ago.
It's about one-fifth as fast as a Lamborghini Gallardo.
In other words, 55 kilometers per hour is 0.170 times the speed of a Lamborghini Gallardo, and the speed of a Lamborghini Gallardo is 5.90 times that amount.
(for Gallardo LP 550-2, a.k.a. Valentino Balboni, 2009 model)
The Lamborghini Gallardo LP550-2 model Gallardo has a top speed of 320 kph. The Gallardo can reach speeds of 100 kph in just 3.9 seconds.
