The answer to this question is 380 minutes
Answer:
10.7 m
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 6,420 m/s
The frequency of the wave, f = 600 Hz
We need to find the wavelength of the wave. We can find it using the below relation as follows :

So, the wavelength of the sound wave is equal to 10.7 m.
To find a percentage, if I am ready your question correctly, would be as simple as dividing the number by 100. For example, finding the percentage of 73.
73/100 = .73%
You could also just move the decimal place over two spots to the left.
