If it takes 3 brick layers 6 hours to build a wall how long would it take 2 brick layers to build the same wall?
I think that'd be 8 hours. 6/3 = 2 hours/worker. One less worker, 2 more hours.
_____________________________________________________________________
nine hours
Each bricklayer can complete 1/3 of the wall in 6 hours.
Two brick layers can complete 2/3 of a wall in 6 hours (2 x 1/3).
To complete the other 1/3 of the wall, the two brick layers would need another 3 hours.

Eight workers can build a cabin in 60 hours. How many workers are needed if the cabin is to be built in 32 hours?
Since we are given no information to the contrary, the following discussion assumes that all men are created equal, and every worker accomplishes the same amount of work in the same amount of time. Since 8 workers can build a cabin in 60 hours, the job comprises (8 man) times (60 hours) = 480 man-hours of labor. That doesn't change. Now however, 480 man-hours of labor must be completed in 32 hours. The number of workers required to accomplish this is (480 man-hours) divided by (32 hours) = 15 man.
If it takes 3 men 6 hours to dig 12 holes how long does it take 2 men to dig 9 holes?
It takes 3 x 6 = 18 man hours to dig 12 holes. Therefore it takes 18/12 = 1.5 man hours to dig 1 hole. To dig 9 holes takes 9 x 1.5 man hours = 13.5 man hours If 2 men are working then they take 13.5/2 = 6.75 hours or 6 hours 45 minutes.

How long does it take for GM Motors to build a vehicle at the assembly line?
Well I have been through the GM plant. It takes about 2 hours from start to finish.AnswerIt takes a little longer then 2 hours to build a complete vehical. A vehical may come off the line about every 3 to 8 minuts, but it takes about 2 day to build a vehical from start to finish. When I worked at the GM plant in Moraine, Ohio a truck rolled of the line every 47 seconds, not 3 to 8 minutes. A truck was made, start to finish, in about 20 hours (if I remember correctly)
