Question

sound travels through dry air at the rate of 343.2 meters per second.Create an equation anf table to show the distance (d) that sound travels during any given length of time (t).

Answer 1

ANSWER and EXPLANATION

We have that the speed of sound through dry air is 343.2 meters per second.

The formula for speed is:

`\text{speed = }(dis\tan ce)/(time)`

This means that distance is:

`\begin{gathered} \text{distance = sp}eed\cdot\text{ time} \\ d\text{ = s }\cdot\text{ t} \end{gathered}`

So, we have that:

d = 343.2 * t

That is the equation that can be used to find the distance at any given length of time.

For the table, we will use values of time ranging from 1 second to 4 seconds.

We have:

=> when t = 1 second:

d = 343.2 * 1

d = 343.2 m

=> when t = 2 seconds:

d = 343.2 * 2

d = 686.4 m

=> when t = 3 seconds:

d = 343.2 * 3

d = 1029.6 m

=> when t = 4 seconds:

d = 343.2 * 4

d = 1372.8 m
