Answer:
0.029 s
Explanation:
The speed of sound in aluminim is v = 5100 m/s.
The sound travels in aluminium by uniform motion (constant speed), so we can find the time it takes to cover a certain distance by using the equation:
[tex]t=\frac{d}{v}[/tex]
where d is the distance covered, in this case d = 150 m. Substituting the numbers into the equation, we find
[tex]t=\frac{150 m}{5100 m/s}=0.029 s[/tex]
