B. 285 km/5 min
Explanation:
The rule that links velocity, wavelength and frequency is:
V = λν
where:
V is the velocity that we want to find
λ is the wavelength of sound = 1 m
ν is the frequency of the wave = 950 Hz
Substitute to get the velocity as follows:
V = 1 * 950 = 950 meters/sec
Now, we need to convert the meter/sec into Km/5 minutes
We know that:
To convert from meter to Km, we will divide by 1000
To convert from sec to minute, we will divide by 60 which means that, to convert from sec to 5 minutes, we will divide by 5*60 = 300
Based on this:
Hope this helps :)
