On a particular day, the wind added 4 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 4 miles pe

allochka39001 [22]

recall your d = rt, distance = rate * time.

j = Jaime's rate

so with the wind her rate is j + 4, and without the wind her rate is j - 4, we also know that she can do with the wind 34 miles and against it 18 miles all within the same amount of time of t hours.

$\bf \begin{array}{lcccl} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\ &------&------&------\\ \textit{with the wind}&34&j+4&t\\ \textit{against the wind}&18&j-4&t \end{array} \\\\\\ \begin{cases} 34=(j+4)t\implies \frac{34}{j+4}=\boxed{t}\\\\ 18=(j-4)t\\ -------------\\ 18=(j-4)\left( \boxed{\frac{34}{j+4}} \right) \end{cases} \\\\\\ 18(j+4)=(j-4)34\implies 18j+72=34j-136 \\\\\\ 208=16j\implies \cfrac{208}{16}=j\implies 13=j$
