The speed of sound varies greatly, depending on the material it goes through - in some cases, by a factor of 5 or more. The speed of sound in air will depend slightly on temperature, pressure, etc., but it is about 340 meters/second. I'll leave it up to you to convert that to mph.

∙ 8y agoThe speed of sound at sea level at 15 degree celsius is calculated to be 761.2 mph or 1225 km/h.Speed of sound varies with altitude and temperature. So this speed varies when conditions change. So this answer is not comletely correct.

How many mph is into the speed of sound?
In dry air (68F) the speed of sound is 343 meters per second
The word Velocity has to do with Speed Sound Distance Thickness Weight?
Velocity is a vector quantity that measures speed (and also includes direction). 55 mph is a speed. 55mph North is a velocity.
What is mach 4 speed?
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
What is the average speed of 40 mph and 60 mph?
Average speed is 50 mph [(40+60)/2].
If 2 identical cars crash and each is traveling at 50 mph is the impact speed 50 mph or 100 mph and why?
The impact speed for each car is 50 mph. During the crash, both cars are accelerated from a speed of 50 mph to zero, hence the impact speed is 50 mph. The relative speed between each car, however, is 100 mph.
Speed of sound in mph?
The speed of sound in MPH is 768 at 20C in dry air.
How many mph can a piano sound wave go?
About 750 mph. The speed of sound.
Is the speed of sound faster or slower than light?
Way slower. For reference, the speed of sound is about 767.3 mph and the speed of light is 671,000,000 mph.
What exactly is the speed of sound?
1337 mph
What is the speed of light and sound in mph?
Speed of light (in vacuum)= approx 671,000,000 mph.Speed of sound (in air at sea level) = approx 760 mph.
Can I run at the speed of sound?
Nope. The speed of sound is ABOUT 760 mph. Fastest human runner is 27.79 mph. Not even close.
The speed of sound in air is always close to?
The speed of sound at sea level is approximately 750 mph.
Speed of sound is maximum?
around 3000 mph
Can tornadoes travel faster then the speed of sound?
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.
How many mph is into the speed of sound?
In dry air (68F) the speed of sound is 343 meters per second
How fast is sonic speed?
Sonic speed which is known as Mach 1 is the speed of sound which is 761 mph.
How fast is mach 20?
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!
