How fast is 0.0278 miles per second?

Sort Order:
Closest first | Highest first | Lowest first

It's about three-fifths as fast as a Skydiver (headfirst)
In other words, 0.0278 miles per second is 0.620 times the speed of a Skydiver (headfirst), and the speed of a Skydiver (headfirst) is 1.60 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 0.045 miles per second. 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 three-fifths as fast as a Helicopter
In other words, 0.0278 miles per second is 0.5670 times the speed of a Helicopter, and the speed of a Helicopter is 1.760 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 0.049 miles per second. 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 two times as fast as a Gazelle
In other words, the speed of a Gazelle is 0.50 times 0.0278 miles per second.
(for Thomson's Gazelle, a.k.a. Eudorcas thomsoni, a.k.a. "Tommie", a.k.a. "Tommy")
A Thomson's gazelle can reach speeds of up to 0.01 miles per second. The gazelle's speed doesn't match that of its chief predator, the cheetah, but a gazelle's endurance usually ensures an escape in distances greater than 500 m (0.3 mi).
It's about two times as fast as a Hare
In other words, the speed of a Hare is 0.50 times 0.0278 miles per second.
(for European Brown Hare, a.k.a. Brown Hare, a.k.a. Lepus europaeus, a.k.a. Brown Hare)
The European Hare can run at speeds of up to 0.01 miles per second. While speed is a factor in their escapes, hares evade their chief predators — wolves, foxes, and golden eagles — by fleeing in a zigzag pattern.
It's about half as fast as a Lamborghini Gallardo
In other words, the speed of a Lamborghini Gallardo is 2 times 0.0278 miles per second.
(for Gallardo LP 550-2, a.k.a. Valentino Balboni, 2009 model)
The Lamborghini Gallardo LP550-2 model Gallardo has a top speed of 0.055 miles per second. The Gallardo can reach speeds of 0.017 miles per second in just 3.9 seconds.
It's about half as fast as The TGV (train)
In other words, the speed of The TGV (train) is 2 times 0.0278 miles per second.
(Train à Grande Vitesse) (for SNCF TGV Réseau, a.k.a. "Network" model, a.k.a. TGV-R) (maximum speed)
The TGV Réseau sets have a top speed of 0.055 miles per second. The train is capable of travelling the 425 km (264 mi) distance from Paris to Lyon in East-Central France in about two hours.
It's about half as fast as an Arrow (archery)
In other words, 0.0278 miles per second is 0.49890 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 2.004 times that amount.
(250 g arrow fired from 60#/28" bow)
A 250 gram arrow will reach speeds of approximately 0.05572 miles per second 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.
