Question 1106905
{{{D/T=R}}} for distance D, time T, and constant rate of travel R.


r, travel speed if no wind present
w, speed of wind


The speed going WITH the wind is larger than the speed going AGAINST wind.

<pre>
                      SPEED        TIME        DISTANCE

GOING, AGAINST WIND     r-w         4&1/4        1125

RETURN, WiTH WIND      r+w           3           1125
</pre>

Basic System from the problem description:
{{{system(r-w=1125/4&1/4,r+w=1125/3)}}}

-

{{{system(r-w=264.7,r+w=375)}}}


Using Elimination Method,


ANSWER:  {{{system(r=320,w=55)}}}
