Answer: f = 392 hz
v = 343 m/s
wavelength = 343/392 = 0.875 m
hope this helped!
If it is eight meters per second, and the total distance he has to travel is four hundred meters to complete the race, you divide the total length needed to travel by the average speed per second to see the amount of seconds required to complete the race at that speed.
8 meters per second: Speed of runner
400 meters: Total distance
400/8=50
50 seconds to complete the race at the eight of 8m/s.
