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