Wave equation :
Velocity = (Wavelength) X (Frequency)
Wavelength = (Velocity) / (Frequency)
= (150)/(2)
= 75m

OR

This may help :
Frequency = 1 / Time(period)
Wave length = Displacement
Velocity of wave = Velocity.

To find Distance, we know from kinematics
Displacement= (Velocity) X (Time)
= (Velocity) X (1/Frequency)
= (150) X (1/2)
= 75m
