A plane traveled 672 miles each way to Austin and back. The trip there was with the wind. Ittook 7 hours. The trip back was into the wind. The trip back took 14 hours. What is the speed ofthe plane in still air? What is the speed of the wind?

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
