Answer 2

Speed of a swimmer A strong swimmer can swim upwards of 2 to 3 km in an hour. However, at a dead sprint, one can swim at about 10 km/h, with the human record probably somewhere around 14 to 15 km/h. World-class swimmers can swim approximately 5 km in an hour in open water without currents.
