Buoys are placed in the ocean at even intervals away from the beach to help swimmers monitor how far away from the beach they have swum. If a swimmer reaches the third buoy, they have swum out 72 meters. How many meters from the beach is the fourth buoy? Let's think first. Chain of thought:
The buoys are evenly spaced, so the first buoy is 72 / 3 = 24 meters from the beach. Thus, the fourth buoy is 24 * 4 = 96 meters from the beach.
Therefore, the answer is 96.
