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?
The buoys are evenly spaced, so the first buoy is 72 / 3 = <<72/3=24>>24 meters from the beach.
Thus, the fourth buoy is 24 * 4 = <<24*4=96>>96 meters from the beach.
