Bryan is riding his bicycle at a constant speed from school to the library. His distance from school to library in kilometers x hours after leaving school can be modeled by the equation y=20-12x. What is the distance from the school and library in kilometers?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer: a) 56% women

b)44% men
