Seriously? Some simple maths will give you your answer: 1km = 10 * 100m Swimmers take 55 secs to go 100m. Assuming their speed is constant, it would take them 10 * 55 secs to go 1km. 10 * 55 = 550, so it takes 550 secs to travel 1km. Divide this by minutes: (550/60=9.1667) which means that they swim at 9.1667km per hour.
Most likely 18 seconds or slower.
A good time would be 29 seconds.

Ian Thorpe's personal best time in the 100 meters freestyle is 47.84 seconds, which he achieved during the 2001 World Championships in Fukuoka, Japan. This remarkable performance helped solidify his status as one of the greatest freestyle swimmers in history. Thorpe went on to win multiple Olympic medals and set several world records throughout his career.
The downhill skiers' approximate average speed for the 35,000 m course can be calculated by converting the time to seconds (130 seconds) and dividing distance by time. Average speed ≈ 35,000 m / 130 s ≈ 269.23 m/s.
There really isn't an average time because it varies about how fast people are. But I would say around 59.999 seconds?
I think anything under 30 seconds is pretty good.
There are no 25 yard events event at the international level. Typically only very young swimmers (12 years and under) swim 25 yard events. However, given that the world record for the 50 yard freestyle is 18.47 (set by Cesar Cielo at the 2008 NCAA Championships), I would guess that the fastest 25 yard free ever swum would be 9.0 seconds or faster.
