Answer by ankor@dixie-net.com(22740)   (Show Source):
You can put this solution on YOUR website! there were 4 workers that built A WALL IN 5 DAYS
Find how many man-days to complete wall:
4 * 5 = 20 man-days
:
"THERE 10 WORKERS HOW MANY DAYS DID IT TAKE THEM TO BUILd A WALL?
let d = no. of days for 10 guys to do it
10d = 20
d = 2 days for 10 guys to do it
:
:
This is in theory only, usually when you get that many together, at least two of them are goof-offs. If they are city workers, the no. of goof-offs will quadruple.

However, your teacher probably is not interested in the social aspect of the situation, have a Blessed Thanksgiving! C
