[tex]\dfrac{75 miles}{hour} * \dfrac{1 hour}{60 minues} = \dfrac{1.25 miles}{minute}[/tex]

Now you want to set up a proportion.

1.25 miles:1 minute :: x : 15 minutes  Set up the proportion

[tex]\dfrac{1.25 miles}{1 minute}= \dfrac{x }{15 minutes}[/tex]  Cross multiply

1.25 miles * 15 minutes = x * 1 minute

18.75 miles * minutes = x * 1 minute. Divide by minutes

x = 18.75 miles. Answer
