Question 1093796
<br>So many different ways to solve the same problem....!<br>
Here is what I would do.<br>
The trip took 3 times as long going upstream as downstream.  That means her downstream speed must be 3 times her upstream speed.<br>
If b is the speed of her boat in still water, then her upstream speed is b-2 and her downstream speed is b+2.  So<br>
{{{b+2 = 3(b-2)}}}
{{{b+2 = 3b-6}}}
{{{8 = 2b}}}
{{{b = 4}}}
