7. A police officer predicts that the average speed, s, in miles per hour on a certain section of road varies inversely as the number of cars, n, increases. a. If 20 cars on that section of road are moving at an average speed of 35 miles per hour, what is the inverse variation function that describes this relationship?

b. Using the function you found, for what number of cars, n, should the police officer expect the predicted average speed, s, to be greater than 70 mph? ​

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
