About how long does it take for sound to travel 1 Km?

Sound travels about 340m/s

time=distance/velocity

Plese tell the answer

To calculate the time it takes for sound to travel 1 km, we need to know the speed of sound. The speed of sound is influenced by various factors like temperature, humidity, and altitude. In dry air at 20 degrees Celsius (68 degrees Fahrenheit), the speed of sound is approximately 343 meters per second (or 343,000 millimeters per second).

To find the time it takes for sound to travel 1 km, we can use the formula:

Time = Distance / Speed

Plugging in the values:

Time = 1000 meters / 343 meters per second

Simplifying the equation:

Time = 2.91 seconds

Therefore, it takes sound approximately 2.91 seconds to travel a distance of 1 km in normal conditions. However, it's important to note that different factors can influence the speed of sound, so the exact time may vary.
