Use the information to answer the following question. The Chang family is on their way home from a cross-country road trip. The distance from home can be represented in miles after t hours of driving by the function D(t) = 2,280 - 60t. What is the value of D (15) and what does this value represent? O A. 900; the distance from home after driving 15 hours OB. 900; the distance driven in 15 hours C. 1,380; the distance driven in 15 hours OD 1,380; the distance from home after driving 15 hours

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
