World-class swimmers can swim approximately 5 km in an hour in open water without currents. They almost maintain this speed over a 25-km course. The usual result for 25 km is around 5 hours and 15 minutes. In an open-water swim down the river, the speed can easily reach 10 km/h (for example, 88 km in Parana river in 8 hours, 46 minutes).
The top speed of the world's best sprinters is around 2.2 m/s or 8 km/h. This is pure swimming speed. The best performances in the 25-m and 50-m freestyle events indicate slightly better average speed, but this may be due to starting jumps and flip turns.
A simple formula for the max speed for a non planning boat is v=k sqrt(LWL) where k= constant =1,25, LWL=length at waterline in meters and v=velocity in m/s. A 2 m long swimmer thus has an approximate upper limit of 1,25 * sqrt(2) or about 6 m/s. Obviously it gets harder the closer to the limit velocity.

How many hours does it take to swim for 50 yards?
An average human swims at 2 miles per hour, which converts to 3520 yards per hour. So unless you swim really, really slowly, it should take much less than one hour to swim 50 yards. In fact it should take a little less than one minute at average speed.
