Depends on the temperature of the surrounding air through which the vehicle is moving. At 21 degrees Celsius the speed of sound is 770mph.
Between 11,000m and 20,000m, the air temperature is about -60 degrees Celsius which equates to the speed of sound being 660mph.
Originally he was said to be the speed of sound, at 767+ miles per hour at sea level. In Sonic Unleaded the check points would report his speed in excess of 2500 miles an hour. The Sonic Adventure DX manual lists him at least as fast as 3840 miles an hour (hypersonic)
the first super sonic airplane is the Chime-XZA it reached 285,453,086,245,556,,571,123,087,343 mm per hour.
hypersonic speeds, approximately five times or more than the speed of sound ...
no one can. Sonic can run faster than 300 miles per hour!
1000
Tails' real name is Miles Power, which is a pun off of "miles per hour" implying his ability to keep up with Sonic. (Notice how "Miles Power" and "miles per hour" sound the same?) Tails reveals his real name in the Sonic TV series when Tails introduces himself to Chris or his family.
600 miles per hour tops by running and up to 800 miles per hour with extreme gear. in the game sonic unleashed (for xbox 360) he runs at a top speed of 3000 mph.
Light is faster than Sonic the Hedgehog in terms of speed. The speed of light is approximately 186,282 miles per second, while Sonic's top speed is around the speed of sound, which is about 767 miles per hour.
The speed of sound flying varies depending on the altitude, temperature, and humidity. On average, the speed of sound at cruising altitude ranges from approximately 660 to 720 miles per hour.
Can't be, nothing is faster than the speed of light ;)
First let's analyze Sonic. He is as fast as the speed of sound, which means he can run for about 768 miles per hour, He is faster when he creates the Sonic boom. Sonic can still be seen while he's running, which means he isn't that fast. Sonic may be fast, but he is not strong. Sonic's weakness is water. Once Sonic gains all the seven chaos emeralds, he can unlock the form of Super Sonic, he is faster and can jump much higher, however he still can't survive underwater, He also has a ring limit of becoming super. Now let's analyze Goku. Goku is can go as fast as 186,000 miles per second, That means he is faster than Sonic, Goku can't be seen when he travels, which makes him extremely fast. Goku has the Kaiouken which makes his strength, hearing, vision, and agility increase. Goku can also unlock the legendary Super Saiyin, and does not have any limit of sort for the transformation. In conclusion, Goku can kick Sonic's butt any day.
No. His real name is Miles Prower, a play on the phrase "Miles per hour". Sonic and his friends nicknamed him "Tails".
