It's about one-third as fast as The Speed of Sound
The speed of The Speed of Sound is about 767 miles per hour.
(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 767 miles per hour. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 3,350 miles per hour to 3,490 miles per hour in water, depending on its salinity.
It's about three-and-a-half times as fast as a Curveball (baseball)
The speed of a Curveball (baseball) is about 76 miles per hour.
