Question

how long does it take sound to travel 5,880 m through lead?
speed of sound
use the table below to answer the two questions
speed of sound
11
3 seconds
4 seconds
6 seconds
5 seconds

Explanation:

Step1: Recall the formula for time

The formula for time \(t\) is \(t=\frac{d}{v}\), where \(d\) is distance and \(v\) is speed.

Step2: Identify the values of \(d\) and \(v\)

From the problem, \(d = 5880\space m\) (distance). From the table, the speed of sound in lead \(v=1960\space m/s\).

Step3: Calculate the time

Substitute \(d = 5880\space m\) and \(v = 1960\space m/s\) into the formula \(t=\frac{d}{v}\). So \(t=\frac{5880}{1960}\).
