Excuse me but his answer is incorrect. To find the proper rate of change you might have to solve it like you would for slope.
First you would find the points for x = 3 and x = 15 would be (3, 0.08) and (15, 327.68). Then using the slope formula you can find 327.60/ 12. That gives 27.3. So in that case the correct answer is C.
<h2><u>DIRECT RULE OF 3</u></h2>
We use a rule of 3 to solve it.
Let's record the data:
253 miles → 8 hours
x miles → 7 hours
Let's solve:
