Asked by Kip
A sound wave travels a distance 1020 m in 5 minutes. If the length of the three successive crests is 15 m, then calculate the wave speed.
"Length of three crests"? I'm not sure about that. Is the question okay? I'm confused. :/

three crests span two complete waves.
Think of a sine wave. max-max is one wavelength, so max-max-max is two wavelengths.
So, the wavelength is 7.5m
Now use your formula: speed = wavelength * frequency
