The equation that can be used to find the number of miles, m, represented by n inches is m = 40n
Which equation can be used to find the number of miles, m, represented by n inches?
From the question, we have the following parameters that can be used in our computation:
0.5 inch represents 20 miles.
This means that
Scale factor = 20/0.5
So, we have
Scale factor = 40
So, the equation is
m = Scale factor * n
This gives
m = 40n
Hence, the equation is m = 40n
