Use the one your teacher suggested since that is what he/she is expecting. They both give you about the same answer.

Shouldnt it be V=331+0.6(T)?
Our science teacher said that

How about the temperature how to get it?

How about this question:
How long to travel 700 m through the air at 15°C?

Is that really the formula of the speed of sound?Please reply cause i badly need the formula of the speed of sound for my reporting.
Thanks.

Your rounding error left you off by about a meter, 467m is a better answer.

What if I don’t have temperature but I have the speed

You Calculated Very Fast
It Was Helpful to me in my EXAMS
Thank You!!

Question: Could you do this formula but use Kelvin as a unit of measurement for the temperature?
or rather is there a formula which uses degrees Kelvin instead of Celsius?

Before I start watching can someone solve this. What is the speed of sound in air at a room temperature of 36.3 degree celsius?

Next time try to explain it as if this is someone new to the whole topic.. I don't want summerized, i need explanation.

what if were finding time with only temperature and distance??

Thank you for this video, but i still have a question that im struggling to get an answer for..
Does anyone have the actual figures concerning the speed of sound at different atmospheric pressures?

First let me explain the reason for the question.
I want to know the time lag verses air pressure of a gunshot and the sound of the bullet hitting the target.
Most answers to my question just say that altitude (not air pressure) and temperature drop cancel each other out. !!!
Referring to sound waves at altitude... I know that air molecule's move faster with increased temperature., and your video shows the formula to calculate the variation of the speed of sound versus air temperature..

So if the variation in speed is 333 + 0.59 x temp c ..and we know that at an altitude of 1000 meters the average air temperature would be 5.6deg colder, that would reduce the speed of sound by 0.59 x 5.6 deg or 3.304 m/sec we know that at 1000 meters altitude the air pressure would be 114 millibars lower than at ground level. minus 114 millibars.
That would suggest that the speed of sound would have to increase by 3.304 m/sec per -114 mb to cancel out, if the statement that they cancel each other out was true !!!
But to see an "increase of speed by reduction of pressure", is counter intuitive because we are told that sound travels faster through a denser medium !!! The complete opposite.. So it's a false statement..they cant cancel out.

So am i correct in saying that the suggestion of the speed of sound being the same at any altitude as the temp and pressure cancel each other out, is totally false and that the text books are very wrong !!!

I have so far failed, to find a chart that shows variations at sea level of the speed of sound versus air pressure...they all assume the atmospheric pressure is at 1013.25 millibar at sea level and for the sake of calculation simplicity, we are assumed to be standing on the sand at the edge of the sea with an air temperature of 20 deg C when doing any maths !
Assumptions are too often wrong !!!

Back to my problem, i need to know exactly what the speed of sound is at a set temperature and pressure atmospheric, to be able to calculate the speed of the projectile. I can accurately measure the temperature, and the pressure to an accuracy of 1milli bar. but i can't use the value of 3.3 meters per 114 millibars as this would be an incorrect assumption, and i've just proved that this is wrong anyway..

So please can you show me the real figures for the variation of the speed of sound depending on variation of air pressure.

How do you calculate the temperature if you know the distance and the ammount of time the sound travels?

Sound waves travel faster through cold air than warmer air because cold air molecules are more tightly compact than warm air which is more spread apart not the other way around.

What if farenheit is given on the temperature?

The relationship of speed of sound and themperature of air is not linear!

I understand this formula, even though I am in fifth grade, but where did you get 2 in d=933÷2=466m?
