Explain to me ? how do i get the answer

Hello!

As we can see, one inch=30 miles. The easiest way to do this would be to multiply 5.6 by 30.

5.6(30)=168

Just to check, we can write this a proportion and solve.



We cross multiply below and divide by one.

5.6(30)=168/1=168

Therefore, the correct answer is B)168 miles.

I hope this helps!
