**drwls**, Tuesday, October 4, 2011 at 6:56amAssume there are N labels.

Sally mails S labels/h

Eric labels E labels/h

6 S = N

4 S + 4 E = N

4S + 4 E = 6 S

2 S = 4 E

S = 2 E

E is half as fast as S, and woul;d take 12 hours alone.

**serj**, Sunday, October 9, 2011 at 10:39pmRead the second bullet point on the first page, in the bold and italics, at the end of the second sentence.

I seriously, seriously hope you weren't dumb enough to use your real first name. Mine definitely isn't Serj.

time = distance/rate and you set the rate up as (5+x) and (5-x) where x is the wind rate. The distance is obvious. solve for x.
