A swimmer may need to convert an overall distance into a number of laps in a pool.
One lap is the length of the pool (not down and back).
A standard Olympic-sized pool is either 25 or 50 meters in length.
1 yard is 0.9144 meters.
1 mile is 1,609.3 meters = 1,760 yards = 5,280 feet
distance traveled =
= (number of laps) * (length of pool)
number of laps required to swim a distance =
= (distance to be traveled) / (length of pool)
