so we know that the speed off some in a zero degree Celsius is 3 31 meter per second from this will simply use our problem. The speed of sound is 3 31 times square. Root off P bye 2 73 Calvin with the meter per second now at 20 degrees. Since she is, we use this formula 3 31 meter per second times squared off. Our temperature is to 73 plus 20. So that's 193 Kelvin divided by 2 73 Kelvin. And when you plug this into a calculator, it turns out to be 343 meter per second, just as we had expected.
