While anchored in the middle of a lake, you count exactly four waves hitting your boat every 10 s. You raise anchor and start motoring slowly in the same direction the waves are going. When traveling at 1.5 m/s, you notice that exactly three waves are hitting the boat from behind every 10 s. What is the speed of the waves on the lake?
