Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

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!)

Answer 1

The correct answer is 132m.

Answer 2

Don't look now, but the question GIVES you the formula to use, and it GIVES you the numbers to plug into the formula.

The formula to use to find the distance covered by the sound is

Speed = (distance) / (time)

They also give you:

speed = 330 m/s

time = 0.40 second

Stuff the numbers into the formula:

330 m/s = (Distance) / (0.40 second)

Multiply each side by (0.40 second), and you get:

(330 m/s) / (0.4 second) = Distance

825 meters = Distance
