Question

A girl swim 400m in still water and then returns to the initial point (from where she started) in 20 minutes determine the speed of the girl

Answer 1

Answer:

Typical swim practice is grueling. A mile may seem like a lot to swim, but for a competent swimmer, a mile is usually a mere warm-up. A full practice can be anywhere between 3-8 miles depending on the type of practice, the time of the season, and the swimmer.
