The speed of sound is approximately 340.49 m/s or three hundred and forty meters per second at sea level. This can be represented as 1225.04 km/hr or one thousand two hundred and twenty five kilometres per hour. In order to break the sound barrier one will have to break the speed of sound or go faster than the speed of sound to break the sound barrier. Cannon balls and bullets were the first to break the sound barrier and from the start of the Second World War the barrier was being broken by various planes. Modern fighter aircrafts can mostly cross the speed of sound and their flight beyond the speed of sound is referred to as supersonic flight. Conversely speeds less than the speed of sound are called subsonic. It was normally believed that this was an actual physical barrier to be overcome. Even though this is not true a sonic boom that occurs when the sound barrier is broken does affect the life of an aircraft. Concorde was the only commercial passenger plane capable of supersonic flight.

Mach 1, by definition. The actual air speed is about 340 metres per second, or 760 miles per hour, at sea level, but it varies considerably with altitude. Towards the end of WWII, fighter aircraft in dives were approaching Mach 1 and reported sever problems with buffeting and control inversion, so fighter aircraft design had to be modified to operate safely through this transonic region.

You would have to be travelling at roughly 750mph but this can vary and be more

You need to be going 750mph but if you go to a higher altitiude it means less speed to break the barrier because sound travels slower higher

In order to cross sound barrier one has to go faster than the speed of sound. The speed of sound is approximately 340m/s at the sea level it keeps on varying with the difference of altitude. Comparatively older air crafts were not able to remain into there posture and shape and hence they broke into pieces due to air friction while crossing the sound barrier. But most of the modern air crafts that are made using modern physics can remain in there posture while breaking the sound barrier. This is due to the fact that they are more smooth at higher speeds and at higher altitudes and hence they cause lesser air friction.
