8. A plane flew 1,740 km in 6 hours with a tail wind. On the return trip, going into the wind, the
plane flew 570 km in 3 hours. What is the plane's speed if there was no wind? What is the
speed of the wind? Write the system of equations that would be used to solve this problem.

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
