Notice: The speed of sound changes with temperature and
a little bit with humidity − but not with air pressure (atmospheric pressure).
The words "sound pressure at sea level" are incorrect and misleading.
The temperature indication, however, is absolutely necessary. The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.547 feet per second or 13 633.356 inches per second.

How long would it take to travel 144 miles at sonic speed?
Using the speed of sound at sea-level ... approx 343 meters per second ... it would take about 10.25 minutes. _________________________________________________________________ The answer above in incorrect if sonic speed is 343 meters/sec. One mile is 1609.344 meters (exactly) 1609.344 meters/mi x 144mi ≈ 231746 meters in 144 miles 231746 meters divided by 343 meter/sec ≈ 675.6 sec or 11.26 minutes
