A boat can travel 16 Kilometers per hour in still water. The boat travels 15 kilometers down a river and then 15 kilometers up stream. The entire trip takes 5.5 hours. Which equation describes the current, c, of the river? a)
b)
c)
d)

$\frac{16}{15 + c} + \frac{16}{15 - c} = 5.5$
$\frac{5.5}{16 + c} + \frac{5.5}{16 - c} = 15$
$\frac{5.5}{15 + c} + \frac{5.5}{15 - c} = 16$
$\frac{15}{16 + c} + \frac{15}{16 - c} = 5.5$
