What is the total distance the sound has to travel between the moment she claps her hand and the moment she hears the echo?Sace Ver said:Homework Statement
A student stands 86m from the foot of a cliff, claps her hands, and hears the echo 0.50s later. Calculate speed of sound in air.
Known
•86m
•0.50s
Homework Equations
V=331.4+0.606T
The Attempt at a Solution
V=d/t
V=86m/0.50s
V=172m/s
Is that the first step to the problem? If so I'm not quite sure what the next step is.

86m x 2 = 172 bc it is an echo?stockzahn said:Your formula is correct, but the value of the distance you used isn't.
The speed of sound in air is approximately 343 meters per second at room temperature and sea level.
The speed of sound in air increases with an increase in temperature. This is because the molecules in the air move faster at higher temperatures, resulting in sound waves traveling faster.
The speed of sound in air can be affected by temperature, humidity, and altitude. Higher temperatures and humidity can increase the speed of sound, while higher altitudes can decrease it.
Sound waves travel faster in solids and liquids because the particles in these mediums are closer together, allowing sound waves to propagate more quickly.
The speed of sound in air can be measured using a device called a sound level meter, which measures the time it takes for a sound wave to travel a known distance. The speed of sound can also be calculated using the formula: speed = frequency x wavelength.
