Identify the coordinate system you could use to describe the motion of a girl swimming across a rectangulral pool

Rectangular coordinates system

Explanation:

in fact you could use any system but is easier to use the rectangular system because the pool (ussually) is a rectangle, so to use this system first you have to select a origin, if we look the pool from a top view the easiest way is to pick the bottom left cornet as the origin and from there meassure distances as in a coordinated plane, it means if the girl is somewhere in the pool we can tell her position meassuring the horizontal distance to her and then the vertical distance, that means that the position of the girl will look like this (x,y) and if she is moving, x and y will be varying during time like (x(t),y(t)).

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
