A cough travels how many mph?
Coughing is an action the body takes to get rid of substances irritating the air passages, and a cough is usually started to clear a buildup of phlegm (mucus) in the trachea. When a person coughs, air may move through this passage at up to 300 MPH. Source: http://www.nativeremedies.com/ailment/persistent-coughing-info.html

Max Speed = 121 mph
It depends on several factors. Bullet can travel as slow as a few hundred feet per second up to several thousand feet per second. 1000 feet per second is about 682 MPH.
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.
The orbital speed of the Earth is 66,622 mph - 107,218 km/h
It travels at 768mph. I hope this helped ;)
At ground level, about 700 mph.
The average gallop of a horse is 45 mph.
40 knots = 46 mph
80.67 feet every second.
At 30 mph, an object is moving at about 44 feet every second.
if you are traveling for an hour it would be 5280 ft times 9 :)
