Question

Suppose you are sitting at an outdoor band concert. Using the data in the table, how long would it take you to hear the beat of a drummer 85 m away?

Options:
A) 0.1 seconds
B) 0.2 seconds
C) 0.3 seconds
D) 0.4 seconds

Answer 1

To find the time for sound to travel 85 meters, divide the distance by the speed of sound (343 m/s). It takes approximately 0.248 seconds, which is rounded to 0.2 seconds, making option B the correct choice.

Step-by-step explanation:

To calculate the time it would take for sound to travel 85 meters, we can use the formula time = distance/speed. In this scenario, we need to know the speed of sound to find the time it takes for the sound of the drum beat to reach the listener. As the typical speed of sound in air at room temperature is approximately 343 meters per second (m/s), we use this value for our calculation.

Applying the formula, we get time = 85 m / 343 m/s. When you perform this calculation, you get approximately 0.248 seconds. This can be rounded to 0.2 seconds for an answer choice, meaning option B) 0.2 seconds is the correct answer.
