v = fλ
v= 5.0 Hz times 0.5m
v=2.5 m/s
The answer is A. 2.5 m/s .

The correct option is (A) 2.5 m/s

Step-by-step explanation:
Since,

v = fλ ---- (1)

where v = speed of the wave
f = frequency of the wave = 5 Hz
λ = wavelength of the wave = 0.5

Plug in the value in (1):
(1) => v = 5 * 0.5
v = 2.5 m/s
