Objects detected by radar are plotted in a coordinate plane where each unit represents 1 mile. The point $(0,0)$ represents the location of a shipyard. A cargo ship is traveling at a constant speed and in a constant direction parallel to the coastline. At 9 A. M., the radar shows the cargo ship at $(0,15)$ . At 10 A. M., the radar shows the cargo ship at $(16,15)$ . How far is the cargo ship from the shipyard at 4 P. M.?

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
