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. 132 m 825 m 264 m 12 m

Explanation:

Step1: Recall the formula for distance

The formula relating speed (\(v\)), time (\(t\)) and distance (\(d\)) is \(d = v\times t\).

Step2: Substitute the given values

We know that the speed of sound \(v = 330\space m/s\) and the time \(t = 0.40\space s\). Substituting these values into the formula, we get \(d=330\times0.40\).

Step3: Calculate the distance

\(330\times0.40 = 132\space m\).

Answer:

132 m
