What is the approximate speed of sound in air at sea level?

Explanation:
Sound travels through air at a speed that depends mainly on temperature. At sea level, a common rough figure used for quick calculations is about 330 m/s, though the more precise value at typical room temperature (around 20°C) is about 343 m/s. Because this question asks for an approximate value, 330 m/s is a reasonable rounded figure and matches the intent of a simple estimate. The exact speed varies with temperature, humidity, and pressure, but the takeaway is that it’s on the order of a few hundred meters per second, not something like kilometers per hour.
