Answer:
d. 22, 700 m
Step-by-step 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:
Where v is the speed, d is the distance and t is the time. Solving for d, we get:
So, replacing v = 4540 m/s and t = 5s, we get:
Therefore, the answer is
d. 22, 700 m
