2planes leave the airport at the same time traveling in opposite directions. the first plane traveled at an average rate of 30 mph slower than the 2nd plane. after 3 hours the planes were 3150 miles apart.

enter in an equation that can be used to determine when the planes were 3150 miles apart, let x represent the average rate of the second plane.

enter the average rate of change of the 2nd plane

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

step-by-step explanation:

by good luck mark me as brainliest

have a nice day

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
