Approx 28.1 feet.
Time = Distance/Speed = 900/1.5 = 600 seconds = 10 minutes. You would have to be a pretty good club swimmer to maintain that speed for that distance.
90 inches is 2.29 meters.
approximately 1600 meters
3 yards is 108 inches 3 meters is about 118 inches 3 meters is longer by about 10 inches
5'7" = 67 inches = 67/39.37 meters = 1.7 meters

1/2 meter per second. OR 1.12 miles per hour.
i swim a fair bit. an average swimmer will swim 50 metres in about 1 and a half minutes breastroke. maybe 10 seconds faster if front crawl
Unfortunately, this is missing one key piece of information. How fast the swimmer is moving.
400 meters. See, that event is a RELAY, so each swims 400m.
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.
the olympic pools are 50 meters (long course) opposed to the typical short course 25 meters because if an olympic swimmer were to dive into a 25 M pool, they would take one stroke (practically) and hit the other end. if you have watched the Olympics (i am guessing you have), you see they streamline a lot underwater. now imagine the same swimmer diving like that into a shorter pool.... yea
