825 m

1 answer

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.
