The transverse wave shown has a wavelength of 1.5 m and is traveling in the x-direction.

A graph with time in second on the x axis from 0 to 6 and amplitude on the y axis from negative 3 to 3. The wave starts at the origin and the crest goes up to +3, back down through 1 s and all the way down to negative 3. The wave crosses this x axis every second.
How long does it take the wave to travel 6.0 m in the x-direction?

0.13 seconds
0.67 seconds
2.0 seconds
8.0 seconds

Zero crossings every 1.0 s mean the time between successive zeros is T/2 = 1.0 s, so the period T = 2.0 s and f = 0.5 Hz.
Wave speed v = f·λ = 0.5·1.5 = 0.75 m/s.
Time to travel 6.0 m = 6.0 / 0.75 = 8.0 s.

Answer: 8.0 seconds.
