Speed of sound

The average speed of sound is 330 meters per second. Estimate how long it will take to hear the church bell 1 km away. Calculate the distance from what would hear sound after 10 seconds.

Correct answer:

t =  3.0303 s
x =  3.3 km

Step-by-step explanation:

v=330 m/s s=1 km m=1 1000  m=1000 m  s = v t t=s/v=1000/330=3.0303 s
t2=10 s  s2=v t2=330 10=3300 m x=s2 km=s2:1000  km=3300:1000  km=3.3 km=3.3 km
