No time at all
Why would four men want to build a wall if its' already been built by the eight men?
Doesn't make sense to me.

It takes 80 man-hours to build a wall (8 men times 10 hours) So it will take 20 hours for 4 men to build a wall (80 man-hours divided by 4 men).

This question is way to easy so I've been thinking there must be a trick about it. The obvious answer would be 20hrs, but maybe we have to take in account for breaks, lunch x2 for that many hrs etc. So is there a trick? Please do tell :)
As soon as I got done answering and submitting I realized it was already built funny question good job :)
