The time it takes for the boat to bounce up and down once is equal to the time it takes for one wave to pass by the boat, since the wave is causing the boat to move up and down.
Explanation:
The velocity of the waves is 20 m/s, and the distance between two consecutive crests (or troughs) is 200 meters. Therefore, the time it takes for one wave to pass by the boat is:
time = distance/velocity = 200/20 = 10 seconds
So the boat bounces up and down once every 10 seconds.

Answer:
The boat bounces of once in every 10 seconds.
Explanation:
The distance between the two consecutive crests in transverse wave motion is called wavelength.
The boat bounces up, ie, it travels from crest to the consecutive crest along wave motion.
Wavelength =distance between two consecutive crests
ie,
Velocity of wave =20 m/s
Hence, time in one bounce of boat
t= 200/20 = 10s
