To find the number of buoys needed, we need to divide the total distance of the race by the distance between each buoy, and then subtract 1 for the starting point since it doesn't need a buoy.
22.5 miles = 22.5 * 1760 yards (1 mile = 1760 yards) = 39,600 yards
Each buoy is placed every 600 yards.
Total number of buoys needed = (Total distance / Distance between each buoy) - 1
Total number of buoys needed = (39,600 yards / 600 yards) - 1
Total number of buoys needed = 66 - 1
Total number of buoys needed = 65
Therefore, 65 buoys are needed for the swim race.
A swim race has a total distance of 22.5 mi. Race officials want to mark the course every 600 yd with a buoy including one at the finish line. (The starting does not need a buoy.) how many buoys are needed?
