Optimal Workout Distance: Laps in a 15x30 Foot Pool

The answer is 132

Explanations:

A standard 25-meter pool is 82 feet long. So a 15x30 foot pool is about 18% the size of a standard 25-meter pool. It would take about 5.5 laps in the 15x30 foot pool to equal one lap in the standard 25-meter pool. So 15 x 5.5 = 82.5 laps. However, most people who work out in a pool typically swim for about an hour. At a casual pace of 15 seconds per lap, an individual could swim 240 laps in an hour. So 132 laps across a 15 x 30 pool is a reasonable workout and roughly equivalent to an hour swimming at a casual pace in the standard 25-meter pool.
