(773 miles/hour) x (5,280 feet/mile) x (1/3,600 hour/second) / (260 per second)
= (773 x 5,280) / (3,600 x 260) (mile - feet - hour - second / hour - mile - second)
= (4,081,440) / (936,000) feet
= 4.36 feet (rounded)

No; hertz is frequency.Frequency times wavelength equals speed of travel.
The frequency is 1/5 = 0.2 Hertz. The wavelength is irrelevant in this question.
Just multiply the wavelength (in meters) with the frequency (in Hertz) to get the speed (in m/s).
Wavelength = speed/frequency = 30/10 = 3 meters
331/20 = 16.55 meters.And by the way ... The hertz is not 20. The 'frequency' is 20 hertz.
