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

Explanation:

Step1: Use the formula \(d = vt\)

\(d\) is distance, \(v\) is speed, \(t\) is time.

Step2: Substitute values

Given \(v = 330\ m/s\), \(t=0.40\ s\).
\(d=330\times0.40\)

Step3: Calculate

\(d = 132\ m\)

Answer:

B. 132 m
