Question 1054219

A river has a current of 5 mph. It takes Bob half an hour longer to paddle upstream 1.2 miles than to paddle downstream the same distance. What is Bob's rate in still water?
<pre>With the rate in still water being S, solve the following TIME equation: {{{1.2/(S - 5) = 1.2/(S + 5) + 1/2}}} to find S.
