 It's about one-one-hundred-fiftieth as fast as The Speed of Sound. In other words, 272.50 centimeters per second is 0.00794 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 126 times that amount. (in dry air at 20°C)The speed of sound in dry air at 20°C (68°F) is 34,300 centimeters per second. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 150,000 centimeters per second to 156,000 centimeters per second in water, depending on its salinity. It's about one-fortieth as fast as a Peregrine Falcon. In other words, 272.50 centimeters per second is 0.0252 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 39.70 times that amount. (a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)The Peregrine Falcon can reach speeds of up to 10,800 centimeters per second 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-thirty-fifth as fast as The CRH (train). In other words, the speed of The CRH (train) is 36 times 272.50 centimeters per second. (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 9,700 centimeters per second. Theses train can make the 120 km (74 mi) journey from Beijing to Tianjin in about 30 minutes. It's about one-thirty-fifth as fast as a Porsche 911. In other words, the speed of a Porsche 911 is 33.60 times 272.50 centimeters per second. (for Porsche 911 Type 997 GT2, 2007 model)The Porsche 911 GT2 has a top speed of 9,140 centimeters per second. It takes just 7.4 seconds for the GT2 to accelerate to 4,470 centimeters per second. It's about one-thirty-fifth as fast as an Arrow (archery). In other words, 272.50 centimeters per second is 0.03039 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 32.910 times that amount. (250 g arrow fired from 60#/28" bow)A 250 gram arrow will reach speeds of approximately 8,967 centimeters 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. It's about one-thirtieth as fast as a Lamborghini Gallardo. In other words, the speed of a Lamborghini Gallardo is 32 times 272.50 centimeters 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 8,900 centimeters per second. The Gallardo can reach speeds of 2,800 centimeters per second in just 3.9 seconds. It's about one-thirtieth as fast as The TGV (train). In other words, the speed of The TGV (train) is 32 times 272.50 centimeters 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 8,900 centimeters 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.
