When swimming in the ocean if you swim with the current it is easier. Most importantly the salt water increases your buoyancy creating less resistance.
as the gravity lift yous
Less than one, because one length in an Olympic pool is 50 meters.
Depends on the pool, but less than a tenth - unless you are swimming in a paddling pool for babies.

A mile in a 25 yard pool equals 71 lengths or 36 laps (1,760 yards in a mile). A mile in a 25 meter pool equals 66 lengths or 33 laps (1,650 meters in a mile). In a 50 Meter pool, a mile is 1,650 meters, which is 33 lengths or 17 laps of the pool. 2 lengths of a pool equals 1 lap.
Sorry, but swimming in a saltwater pool is a lot different than swimming in the ocean. In the ocean, pollutants like oil, gasoline, and trash combine with fish urine and dead animals. Another big difference in a pool is that there are no waves! In the ocean, rip tides and tidal waves are a big part of the ocean's cycle. In your pool, waves are non-existent.
No. No more than swimming in the ocean will.
if ostriches cant swim, they wount be floating on top of water, which means ostritches can swim.
In an Olympic sized pool at 164ft, swimming from one side to the other side would be about .05km. So, you would have to swim to the opposite side of the pool 30 times to swim 1.5k.Assuming that 164ft is the pool size and one lap is considered swimming to the opposite side of the pool.If you're in a normal sized pool, you would need to swim 60 lengths.
Yes. A hammerhead usually lives in the warmish open ocean and usually swim in packs
If you are a good swimmer it should take you less than 3 minutes in a 25 meter pool
There are 5280 feet in a mile. Thirty-five 150 foot laps takes you 5250 feet. Another 30 feet (less than half the pool) and you're done.
