Asked by Jael
A series of waves traveling at 200 m/sec are being generated by a 100 Hz source. A point at the very top of the crest of a certain wave is ____ meters from a corresponding point 3 crests away.
a. 0
b. 1.5
c 2.7
d 4
e 6
f 12
g 16
h 30,000
I have no clue what the equation would be to find this answer.
I tried 100Hz x 200m/sec x 3, but the answer I got was not an answer choice. Help please!!!

p = 1/F = 1/100 = 0.01 Sec. = 1 period.
3p = 3 * 0.01 s. = 0.03 s.
d = 200 m/s * 0.03 s. = 6 m.
3p = 3 * 0.01 s. = 0.03 s.
d = 200 m/s * 0.03 s. = 6 m.
