Down stream it would be going 20 mph and up stream 10 mph
Answer:
Explanation:
The standard equation of the sinusoidal wave in one dimension is given by

Here, A be the amplitude of the wave
λ be the wavelength of the wave
v be the velocity of the wave
Φ be the phase angle
x be the position of the wave
t be the time
this wave is travelling along positive direction of X axis
The frequency of wave is f which relates with velocity and wavelength as given below
v = f x λ
The relation between the time period and the frequency is
f = 1 / T.
