You can put this solution on YOUR website!
if 20 man can build a wall 112 meters long in 6 days,
find the no. of man-days to complete the 112 m wall
20 * 6 = 120 man-days
find how many man-days per ft
112%2F120 = .933 man-days per ft
:
what length of similar wall can be built by 25 mans??
25 * 6 * .933 = 140 m, by 25 men in 6 days
