Question

How far does sound travel in 5 seconds through glass at 20c

Answer 1

Answer:

d. 22, 700 m

Explanation:

We know that the speed of sound at 20°C is 4540 m/s and the time that the sound traveled was 5 seconds. So, we can use the following equation:

$v=\frac{d}{t}$

Where v is the speed, d is the distance and t is the time. Solving for d, we get:

$d=v\cdot t$

So, replacing v = 4540 m/s and t = 5s, we get:

$\begin{gathered} d=4540m/s\cdot5s \\ d=22,700m \end{gathered}$

Therefore, the answer is

d. 22, 700 m
