Ojos del Salado is the highest mountain in Chile, with a peak at about 6,900 meters above sea level.
• The Atacama Trench, just off the coast of Peru and Chile, is about 8,100
meters below sea level at it's lowest point.
Is the elevation HALFWAY between the peak of the mountain and the
Trench ABOVE OR BELOW sea level? Explain your answer without
calculating the exact value

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

a

the answer is b.
