🤓 Based on our data, we think this question is relevant for Professor Gibbons' class at Midland College.

Solution: A fisherman fishing from a pier observes that the float on his line bobs up and down, taking 2.4 s to move from its highest to its lowest point. He also estimates that the distance between adjacent wave crests is 48 m. What is the speed of the waves going past the pier? (A) 20 m/s (B) 1.0 m/s (C) 10 m/s (D) 5.0 m/s (E) 115 m/s
