Question

A marching band is practicing. The band director sees the drum major hit a drum. How far away is the director if he hears the drumbeat in 0.40 seconds? The speed of sound is 330 m/s.

12 m
132 m
264 m
825 m

Answer 1

To find out how far away the band director is from the drum major, we can use the formula:

\[
\text{Distance} = \text{Speed} \times \text{Time}
\]

Given:
- Speed of sound = 330 m/s
- Time = 0.40 s

Now, substituting the values into the formula:

\[
\text{Distance} = 330 \, \text{m/s} \times 0.40 \, \text{s} = 132 \, \text{m}
\]

So, the band director is 132 meters away from the drum major. The correct answer is **132 m**.
