If it takes 5 men 20hours to brick a house, how long will it take 2 men to do the job if they work at the same rate?

Elden [556K]

To find the contribution of each man (this is a sexist problem as women could work as well, but that’s besides the point) take 5/2 and then multiply that value by 20 and you’ll find it takes 50 hours for two men to do it.

Answer: 50 hours
