 It's about one-six-hundredth as fast as The Speed of Sound In other words, 2 kilometers per hour is 0.00162 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 617 times that amount. (in dry air at 20°C)The speed of sound in dry air at 20°C (68°F) is 343 m/s. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 5,390 kilometers per hour to 5,620 kilometers per hour in water, depending on its salinity. It's about one-two-hundredth as fast as a Peregrine Falcon In other words, 2 kilometers per hour is 0.00514 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 195 times that amount. (a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)The Peregrine Falcon can reach speeds of up to 389 kph when diving. Falcons are sometimes sent to scare smaller birds away from airports to improve air traffic safety and were used in World War II to intercept carrier pigeons used by enemy forces. It's about one-two-hundredth as fast as The CRH (train) In other words, 2 kilometers per hour is 0.0057 times the speed of The CRH (train), and the speed of The CRH (train) is 180 times that amount. (a.k.a. Hexie Hao, 和谐号, a.k.a. 和諧號, a.k.a. Héxié Hào, a.k.a. "Harmony")The CRH-3 train which runs on China's Beijing-Tianjin Intercity Railway are capable of speeds up to 350 kph. Theses train can make the 120 km (74 mi) journey from Beijing to Tianjin in about 30 minutes. It's about one-one-hundred-fiftieth as fast as a Porsche 911 In other words, 2 kilometers per hour is 0.00608 times the speed of a Porsche 911, and the speed of a Porsche 911 is 164 times that amount. (for Porsche 911 Type 997 GT2, 2007 model)The Porsche 911 GT2 has a top speed of 329 kph. It takes just 7.4 seconds for the GT2 to accelerate to 161 kilometers per hour. It's about one-one-hundred-fiftieth as fast as an Arrow (archery) In other words, 2 kilometers per hour is 0.006196 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 161.40 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-one-hundred-fiftieth as fast as a Lamborghini Gallardo In other words, the speed of a Lamborghini Gallardo is 160 times 2 kilometers per hour. (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. It's about one-one-hundred-fiftieth as fast as The TGV (train) In other words, the speed of The TGV (train) is 160 times 2 kilometers per hour. (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 320 kph. The train is capable of travelling the 425 km (264 mi) distance from Paris to Lyon in East-Central France in about two hours.
