What is the formula for calculating the speed of sound?

What is the formula for calculating the speed of sound?

• v: speed (m/s)
• s: distance (m)
• t: time (s)

v=​t​​s​​

Now we are starting with the calculations

• Apply the problem solving procedure.
• You're always allowed to use a calculator.

Miss Mulder has setup an experiment to measure the speed of sound. Mister Brands stands 686 meters away from her and hits two wooden planks together to produce a loud sound. It takes 2 seconds before Miss Mulder hears the sound. According to the data of this experiment, what is the speed of sound?

Given:

s = 686 m

t = 2 s

Asked:

Calculate the speed of sound

Formula:

v=s/t

Calculation

v = 686/2 = 343 m/s

Answers

The speed of sound is 343 m/s

What is the speed of sound?
