Close to 500 to 1000 meters long.
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
1000 meters is 1000 meters long. If you would like it converted to another unit of measure, please specify.
1000 metres, I guess!
It is 1000 meters long
How long it takes to swim 1500 meters depends entirely on how fast a swimmer you are. For me it takes 20-25 minutes.
It is debatable about what an average person is. An average swimmer can swim 2640 yards in about 30-50 minutes. It just depends if they are a swimmer.
