Speed of sound per hour?
The speed of sound in air is approximately 343 meters per second. To convert this to miles per hour, multiply by 3600 seconds in an hour and then divide by 1609 meters in a mile. The speed of sound in air is roughly 767 miles per hour.
How many mph does sound travel?
The speed of sound at 20°C is 343 m/s or 1236.3 km/h all over the world. In USA they need for the speed of sound at 68 degrees Fahrenheit 1126.713 feet per second or 768.2 miles per hour. Important is the temperature.
Which travel faster light or sounds?
Light travels considerably faster.Sound travels at about 343 meters per second. Light travels at 299,792,458 meters per second.Light in vacuum travels about 876 thousand timesas fast as sound in air.If you meant to ask if light or sound travels faster then this is the answer:Light travels faster, with a speed of 300,000,000 m/s (which is equal to 300,000 km/s, or 186,282 miles per second). Sound, on the other hand, travels at a speed of 340 m/s (which is equal to 1126 ft/s).
What is speed of sound in air at 72 degrees?
