272.50 centimeters per second is about one-one-hundred-fiftieth as fast as The Speed of Sound
In other words, it's 0.00794 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 126 times that amount.
(in dry air at 20°C)
The speed of sound in dry air at 20°C (68°F) is 34,300 centimeters per second. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 150,000 centimeters per second to 156,000 centimeters per second in water, depending on its salinity.
