A skipper on a boat sees wave crests passing the anchor chain every 5 seconds and estimates the distance between crests is 15 m. What is the speed of the water waves?
A)3 m/s
B)5 m/s
C)15 m/s
D)need more information

The speed of the water waves can be calculated using the formula speed = distance/time. Here, the distance between crests (which can be considered the wavelength) is 15 m, and the time it takes for a crest to pass is 5 seconds. Therefore, the speed = 15 m / 5 s = 3 m/s.
