Question 770632
Which Way_________rate___________time____________distance
WITH______________r+w____________8_______________6312
AGAINST___________r-w____________8_______________4792


r = speed with no wind
w = speed of wind

rate*time=distance key idea.


{{{(r+w)*8=6312}}} and {{{(r-w)*8=4792}}}
Two linear equations in two unknowns.  Solve for r and w.
