Question 1052683
Rowing affected by a tailwind?   Tailwind changes directions when rowing in the opposite direction?  Here is taking the description just as it is written, even though the "tailwind" is so small.  Is the speed of x, in the absence of the tailwind?


<pre>
                SPEED            TIME           DISTANCE
OUT TO          x+4               t              20
RETURN          x+4               t              20
total                             5              40
</pre>

Both directions take the same values.
{{{2t=5}}}
{{{t=2&1/5}}}
-
{{{(x+4)*5=20}}}
{{{x+4=20/5}}}
{{{x+4=4}}}
{{{x=0}}}--------------Ryan is just sitting in the boat, NOT rowing, and the tailwind is doing all the work.
