David will finish first, because if you divide Brad's miles by 2 to his miles in a 1/4 of an hour are 5.95 miles. This means David went 6.2 miles in the same time that Brad went 5.95. Therefore, David will finish first.

$p + q = \frac{2u}{1 - u} + \frac{1 + u}{1 - u} = \frac{1 + 3u}{1 - u}$

$p - q = \frac{2u}{1 - u} - \frac{1 + u}{1 - u} = \frac{u - 1}{1 - u}$

$\frac{p + q}{p - q} = \frac{1 + 3u}{1 - u} \div \frac{u - 1}{1 - u} = \frac{1 + 3u}{1 - u} \div (- 1) = - \frac{1 + 3u}{1 - u}$
