Answer:
Step-by-step explanation:
If the speed of sound in air at a certain temperature is 343 m/s, and it takes 0.200 seconds for the siren to arrive at your school, we can use the formula distance = speed * time to find the distance from the firehouse to your school:
distance = speed * time
distance = 343 m/s * 0.200 s
distance = 68.6 m
So the school is 68.6 meters away from the firehouse.
