However, it's important to note that this is just an average. The speed of sound can vary slightly depending on factors like:

* Temperature: Sound travels faster in warmer air.

* Humidity: Sound travels slightly faster in humid air.

* Altitude: Sound travels slightly slower at higher altitudes.

So, while 767 mph is a good general approximation, the actual speed of sound at sea level could be slightly higher or lower depending on the specific conditions.
