In the ninth grade math contest, we learned the inverse proportional function. For example, when the area of a rectangle is constant, the length A is the inverse proportional function of the width B, and the functional relationship can be written as (S is constant, S≠0). According to the above, please give another example of inverse proportional function in daily life, production or study, and write an example of relationship: functional relationship: as shown in the figure, the primary function is known. Two points b and the image of the inverse proportional function intersect at point C in the first quadrant, CD ⊥ X axis, and the vertical foot is D. If OA=OB=OD= 1, the inverse proportional function is analyzed. ...
