8.46 seconds- Michael phelps
to swim 400 meters in a 25 METER pool, you must swim 16 lenghts, but to swim 400 meters in a 25 YARD pool, you must swim 17.5 lengths (so just swim 18 lengths)
With a dive a good club swimmer can swim 25 meters in around 10 - 11 seconds. An average swimmer should bbe able to swim 25 meters in around 20 seconds
Yes, it is the fastest. It can swim at speeds over 25 mph.
2.6 million people can swim 25 meters enjoy :)
500 meters equals just less then 550 yards. 550 divided by 25 is 22. You would have to swim about 22 laps in a 25 yard pool to swim 500 meters.
Most likely 18 seconds or slower.
210 times 25 meters=5,250 meters (or 5.25 kilometers)
as fast as one can burn it
There aren't usually records in the 25 freestyle because after you turn 9, you never swim it again.
How long it takes to swim 1500 meters depends entirely on how fast a swimmer you are. For me it takes 20-25 minutes.
