Speed of sound in air at 20°C or 68°F is 343 m/s that equals 0.21313 mi/s. In an hour is must be 3600 times more, that is 763.632 mi/h. Cheers ebs
It should be noted that the speed of sound is dependent on the density of air. Temperature, humidity and altitude all affect what the speed of sound might be at any place on Earth. Usually for non-specific use, the sea-level measurement with a temperature of 15 °C (59 °F) is used - 1,225km/h or 761mph is used. At 20,000m(where most commercal jets fly) it is 1,062km/h or 660mph at −57 °C (−70 °F).
Unusual amounts of particlate matter(dust, dirt, sand, etc.) can also affect the speed of sound, as well as abnormal gas mixtures(such as over volcanic vents).
In air at 20 degrees celsius sond travels at 1,236 Kmph and 768 mph
Inorder to figure the speed at different temperatures use the following equation:
V(speed)=331+temperature (in Celsius) times .6
In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s). This is 1,236 kilometres per hour (768 mph), or about one kilometer in three seconds or approximately one mile in five seconds.
add sound travels at different velocities in different materials. The velocity is given by (R/d)(0.5) where R is the elastic constant for the material, and d is the density. It travels about 13km/sec in Beryllium (the fastest), and requires a medium for its transport. It thus will not travel in a vacuum.
At sea level, sound travels at .211446403 miles per second.
The speed of sound in air at 25 oC (77 oF) is 776.496 mi/h. The speed of sound varies with temperature and medium.
About 760 mph
0.211 miles per second.
768.095 mph
Mach 20= 15,200 miles per hour.Mach numbers are determined by the speed of the object divided by the speed of sound.The speed of sound is approx. 760 miles/hour - a Mach 1 number would be the speed of the object (760 mph) divided by the speed of sound (760 mph) = 1Mach 20 would be 20 times the speed of sound (760 mph) = 15,200 mph.It is absurd to think that the government just lost an aircraft flying at the speed of 700 billion mph!
Mach refers to the speed of sound, for example, mach 1, equals the speed of sound, mach 2, the speed of sound times 2. So, mach 25 would mean, 25 times the speed of sound.
depends on several factors. the speed of sound is 343 meters per second (1,125 feet/s). This equates to 1,236 kilometers per hour (768 mph), or about one kilometre in three seconds and about one mile in five seconds.
It depends on the substance the sound is traveling through. If the sound is traveling through air, it is usually about 800km/h. If it is traveling through water, the speed is about 4000km/h. If it is traveling through cosmos, its speed is 0km/h.
850 mph = 379.98 meters per second.
The speed of sound in MPH is 768 at 20C in dry air.
About 750 mph. The speed of sound.
Way slower. For reference, the speed of sound is about 767.3 mph and the speed of light is 671,000,000 mph.
1337 mph
Speed of light (in vacuum)= approx 671,000,000 mph.Speed of sound (in air at sea level) = approx 760 mph.
Nope. The speed of sound is ABOUT 760 mph. Fastest human runner is 27.79 mph. Not even close.
The speed of sound at sea level is approximately 750 mph.
around 3000 mph
No. The fastest speed a tornado has peen known to travel is 73 mph, about 1/10 the speed of sound. The fastest wind speed ever recorded in a tornado was 302 mph, still less than half the speed of sound.
In dry air (68F) the speed of sound is 343 meters per second
Sonic speed which is known as Mach 1 is the speed of sound which is 761 mph.
