Question

On Alex's map, 0.5 inch represents 20 miles.

Which equation can be used to find the number of miles, m, represented by n inches?
A
m = = 0.5 (20n)

Answer 1

Answer: I think it A because the other ones doesn’t make sense

Explanation:

Answer 2

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
