A swim race has a total distance of 30 mi. Race officials want to mark the course every 825 yd with a buoy, including one at the finish line. How many buoys are needed?

I believe 88 buoys

Step-by-step explanation:

Step-by-step explanation:

The race is 25 miles long and theirs a buoy every 500 yards

There are 44000 yards in 25 miles

44000 (yards) divided by 500 (yards) is 88 (buoys).

500 yards      44000 yards

=  

1 buoy              x buoys

Going diagonally, 1 × 44000 is 44000.

44000 ÷ 500 = x

x = 88
