Answer:
The speed of sound through air varies with temperature. At -16°C, the speed of sound through air is approximately 320 meters per second.
To find the distance the sound wave has moved in 19 seconds, we can use the formula:
distance = speed x time
distance = 320 m/s x 19 s
distance = 6,080 meters
Therefore, the sound wave has moved 6,080 meters in 19 seconds through air at -16 degrees Celsius.
