You and your surfing buddy are waiting to catch a wave a few hundred meters off the beach

The waves are conveniently sinusoidal, and you notice that when you're on the top of one wave and moving toward your friend, she is exactly halfway between you and the trough of the wave. 1.50 seconds later, your friend is at the top of the wave. You estimate the horizontal distance between you and your friend at 8.00 m. (a) What is the frequency of the waves? (b) Find the speed of the waves. What will be an ideal response?
