What Is the speed of sound in mph?
Answer:
The speed of sound in mph is 767 mph.
We know that the speed of sound in air is a constant value of 344 m/s.
The medium in which sound travels and its warmth both affects how fast it travels. In dry air at 20° C sound moves at 344 m/s.
The speed of sound in miles per hour at 20° C in dry air is about 767.2 miles per hour. The speed in metres per second must be multiplied by 2.2 to equal the speed in miles per hour. So, if sound is travelling through dry air at 20° C the speed in meters per second is 344 m/s. That results in a speed of 767 miles per hour when divided by 2.2.
