 It's about 1,500 times as fast as The Speed of Sound. In other words, 526 kilometers per second is 1,530 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 0.000654 times that amount. (in dry air at 20°C)The speed of sound in dry air at 20°C (68°F) is 0.3430 kilometers per second. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 1.50 kilometers per second to 1.560 kilometers per second in water, depending on its salinity. It's about 5,000 times as fast as a Peregrine Falcon. In other words, 526 kilometers per second is 4,870 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 0.000205 times that amount. (a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)The Peregrine Falcon can reach speeds of up to 0.1080 kilometers 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 5,500 times as fast as The CRH (train). In other words, the speed of The CRH (train) is 0.00019 times 526 kilometers 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 0.097 kilometers per second. Theses train can make the 120 km (74 mi) journey from Beijing to Tianjin in about 30 minutes. It's about 6,000 times as fast as a Porsche 911. In other words, 526 kilometers per second is 5,750 times the speed of a Porsche 911, and the speed of a Porsche 911 is 0.000174 times that amount. (for Porsche 911 Type 997 GT2, 2007 model)The Porsche 911 GT2 has a top speed of 0.0914 kilometers per second. It takes just 7.4 seconds for the GT2 to accelerate to 0.0447 kilometers per second. It's about 6,000 times as fast as an Arrow (archery). In other words, 526 kilometers per second is 5,866 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 0.0001705 times that amount. (250 g arrow fired from 60#/28" bow)A 250 gram arrow will reach speeds of approximately 0.08967 kilometers 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 6,000 times as fast as a Lamborghini Gallardo. In other words, 526 kilometers per second is 5,900 times the speed of a Lamborghini Gallardo, and the speed of a Lamborghini Gallardo is 0.00017 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 0.089 kilometers per second. The Gallardo can reach speeds of 0.028 kilometers per second in just 3.9 seconds. It's about 6,000 times as fast as The TGV (train). In other words, 526 kilometers per second is 5,900 times the speed of The TGV (train), and the speed of The TGV (train) is 0.00017 times that amount. (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 0.089 kilometers 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.
