Answer:

750m/s

Explanation:

The wavelength of a wave can be calculated by using the formula:

λ = v/f

Where;

λ = wavelength (m)

v = speed of wave (m/s)

f = frequency (Hz or s-¹)

According to the information provided on the wave in this question, λ = 5m, f = 150Hz, v = ?

v = λf

v = 5 × 150

v = 750m/s

Hence, the velocity of the wave is 750m/s.
