 It's about three-fourths as fast as a bolt of Lightning In other words, the speed of a bolt of Lightning is 1.40 times 45 miles per second. (atmospheric electrical discharge)A bolt of lightning can travel at up to 60 miles per second when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year. It's about one-and-seven-tenths times as fast as a Meteor In other words, the speed of a Meteor is 0.590 times 45 miles per second. (formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")Small meteoroids enter the Earth's atmosphere at speeds between 6.90 miles per second and 45 miles per second, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 1.70 miles per second. It's about nine-and-a-half times as fast as The Space Shuttle In other words, 45 miles per second is 9.35230 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 0.106930 times that amount. (Orbiter vehicle velocity)The space shuttle orbits at a speed of 4.81170 miles per second. During liftoff, the space shuttle accelerates to orbital speed in 8.5 minutes, consuming over 1.59 million kg (3.51 million lbs) of propellant in the process. It's about 80 times as fast as a Bullet (Rifle) In other words, 45 miles per second is 79.10 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 0.0126 times that amount. (5.56 x 45 mm, a.k.a. 5.56 NATO)A 5.56 x 45 mm cartridge is fired at a velocity of 0.5690 miles per second. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces. It's about 100 times as fast as a Jet Fighter In other words, 45 miles per second is 110 times the speed of a Jet Fighter, and the speed of a Jet Fighter is 0.0091 times that amount. (for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)An F-16's maximum speed at altitude is approximately 0.420 miles per second. The F-16 has a flight ceiling of approximately 15 km (9.32 mi). It's about 200 times as fast as a Bullet (Handgun) In other words, 45 miles per second is 189 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.00529 times that amount. (for .40 Smith & Wesson 135 grain Sierra JHP, VV 3N37 powder, Fed. 100 primer, Remington case) (muzzle velocity)A 0.40 caliber Smith & Wesson bullet has a muzzle a velocity of 0.2380 miles per second. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990. It's about 200 times as fast as The Speed of Sound In other words, 45 miles per second is 211 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 0.00474 times that amount. (in dry air at 20°C)The speed of sound in dry air at 20°C (68°F) is 0.2130 miles per second. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 0.930 miles per second to 0.9690 miles per second in water, depending on its salinity.
