Correct answer only !

on a cold winter morning, sound travels at only 330 m/s. you yell “hello” to your neighbor and they hear you after 0.40 seconds. how far away is your neighbor?

use the equation v=dt.

(hint: make sure you plug your numbers in for the correct variables! )

Velocity = distance / time

So: The time in which the wave propagates through air which is its medium along with the distance the wave travels so a point are needed to give us our velocity.

In this case we only have velocity and time

So lets rearrange our equation to fit what we are solving for: distance

Vt = d

Now plug in our values:

(330)(0.40) = d

d = 132 m

So the distance between you and your neighbor is 132 m as they perceive the sound at time t= 0.4 and a speed of sound of 330 m/s.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
