3,600,000 yards per hour is about two-and-a-half times as fast as The Speed of Sound.
In other words, it's 2.670 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 0.3750 times that amount.
(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 1,350,000 yards per hour. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 5,890,000 yards per hour to 6,140,000 yards per hour in water, depending on its salinity.
