Well for a competitive swimmer in longcourse it should be about 4-6 ( depends on age an level) so the average person that doesn't practice swimming probably 15 minutes if they could even finish it( depending on how physically fit they are and how their general technique is in swimming) 400 meters is a lot for someone who doesn't swim- thats 16 laps in a shortcourse pool and 8 in a longcourse.
Swimming in a 25 meter pool, you would need to swim 16 laps. It is 440 yards, or 17.6 laps in a 25 yard pool. If it takes a swimmer 2 minutes to swim 100 meters, then it would take that swimmer about 8 minutes to complete.
If it takes you 2 to 3 minutes to swim 100 meters, then it would be between 8 and 12 minutes of swimming. It just depends on how fast a swimmer you are.
400 meters = 437.45 yards

The 1500m swim is considered the mile race, so pretty close.
It depends on his/her age and how fast is he/she.
