It's about four-and-a-half times as fast as an Arrow (archery).
In other words, 745 knots is 4.2740 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 0.2340 times that amount.(250 g arrow fired from 60#/28" bow)
A 250 gram arrow will reach speeds of approximately 174.30 knots 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 four-and-a-half times as fast as a Lamborghini Gallardo.
It's about four-and-a-half times as fast as The TGV (train).
In other words, the speed of The TGV (train) is 0.230 times 745 knots.(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 170 knots. 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 five times as fast as a Helicopter.
In other words, 745 knots is 4.860 times the speed of a Helicopter, and the speed of a Helicopter is 0.2060 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 153 knots. 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 Skydiver (headfirst).
In other words, the speed of a Skydiver (headfirst) is 0.190 times 745 knots.(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 140 knots. 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 seven times as fast as a Tornado.
In other words, 745 knots is 6.9419490 times the speed of a Tornado, and the speed of a Tornado is 0.14405180 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 95.587390 knots and 119.0497 knots. 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 seven times as fast as a Skydiver (belly-to-earth).
In other words, 745 knots is 7.20 times the speed of a Skydiver (belly-to-earth), and the speed of a Skydiver (belly-to-earth) is 0.140 times that amount.(Belly-to-Earth orientation, average conditions, terminal velocity)
A belly-to-Earth oriented skydiver's terminal velocity is about 100 knots. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 60 seconds.
