Now, WRITE IT DOWN!!

Distance = Rate * Time

8 Mile = X mph * Time

16 Mile = (X mph + 9 mph) * Time

We know already that "Time" is hte same in each.

Now, what on earth is that 1/8 mph business? First, it takes 64 hours to get 8 miles at this speed. Second, the units aren't even mph. What are they? It is all very confusing. Never do that. Third, you're going to get a lot more than 16 miles at 9.125 mph for 64 hours. You do need to make sure your answers make sense.
