Question 679647: if 5 men can build a house in 16 days then how long ll it take just 2 men to build the same house
Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! 5 men can build a house in 16 days
Twice as many men can build the house in half the time, so
10 men can build a house in 8 days
1 man will take 10 times as long to build the house, so
1 man can build a house in 80 days
2 men can build the house in half that time, so
2 men can build a house in 40 days
