There are 5280 feet in one mile. Therefore, 28 miles is equal to 28 x 5280 = 147840 feet.
28 miles per hour = (28 x 5280 feet)/(60 x 60 seconds) = 41.0667 feet per second
28 feet per second = 19.09 mph (approx).
1 mile = 5280 feet. 5280 x .28= 1478.4 feet

Circumference of the pool = 28*pi feet
28 inches 2.3333333333 feet.
The answer will depend on the units for 28 and 60. Are they both feet, or is one inches and the other miles, or are both yards? Who knows? The question does not give any clues!
