speed of sound [air] to mile/hour (mph) (c to mph) - Speed Conver…
Speed of sound through air (gas) = 343 m/s or 767 mph. Speed of sound through water (liquid) = 1,482 m/s or 3,315 mph. Speed of sound through steel (solid) = 5,790 m/s or 12,950 mph. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.

The first version is apparently the one enacted by HB 1075. This bill had the sole practical effect of authorizing the 70 MPH speed limit for passenger vehicles towing motorcycle or dog trailers. Otherwise these vehicles may have been subject to a 60 MPH maximum speed limit intended for trucks. The second version is the one enacted by HB 676.

A jet fighter pilot wishes to accelerate from rest to 5g to reach Mach 3 (three times the speed of sound) as quickly as possible. Experimental tests reveal that he will blackout if this acceleration lasts for more than 5.0 s. Use 331 m/s for the speed of sound. (a) Will the period of acceleration last long enough to cause him to black out? (b)
