It takes 10 laps in an 50m Olympic size swimming pool and 20 laps in a 25m long swimming pool. A lap = a length. It's confusing because on a track, a lap is an oval path around the track back to the starting point.

It depends on which pool you swim in. If it is a 25m pool then it will take 20 laps to finish but if it is in a 50 meter pool, which is Olympic size, it will be 10 laps to do 500 meters.
