Answer: 9.09 seconds

Explanation:

Given that,

speed of sound = 330 m/s

Distance away = 3 km

(since the SI unit of distance is metres, convert 3km to metres

1km = 1000 metres

3km = (3 x 10000) = 3000 metres

Time it take for the sound to reach you = ?

Now, recall that speed is obtained by dividing distance travelled by the time taken.

i.e speed = distance / time

330 m/s = 3000 m / time

Time = 3000 m / 330 m/s

Time = 9.09 seconds

Thus, it will take 9.09 seconds for the sound to reach you.
