It takes the time for the wave to travel 6.0 m in the x-direction is 8s.
The wavelength λ is the distance between the adjacent crest or trough.
Given the wavelength is 1.5 m.
λ/2 = 1 s
1.5/2 =1 s
0.75 m in 1 s is traveled by the wave.
To travel 6m , the time required is
= 6/0.75
=8s
Thus, it takes the time for the wave to travel 6.0 m in the x-direction is 8s.
