A small private airplane traveled 140 miles in the same amount of time it took a helicopter to travel 95 miles. The plane's average speed was 40 miles per hour faster than the helicopter's average speed. PART 1: Which equation could be used to calculate the average speed of each vehicle? A. 140 95 B. 95 x + 40 Y Y + 40 C. 140x = 95x + 40 D. 40. 235​

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

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

think the answer would beb
