It is given in the question that,
The speed of sound is 1088 feet per second at sea level at 32° f.
It means , in one second, sound travels a distance of 1088 feet.
And we have to find the distance travelled by sound after 8 seconds.
Therefore, after 8 seconds, the sound travels
[tex]=1088* 8 feet = 8704 feet[/tex]
