If 5 machines can make 12,000 widgets in four 8-hour working days, then how similar machines can make 150 widgets in one hour? Thank you for help.

12,000 / 5 machines/4 days / 8 hours =75 widgets per machine per hour. therefore it takes.

150/75=2 machines required for 1 hour.

5 machines can make 12,000 widgets in four 8-hour working days

 

So....

 

5 machines can make 12000 widgets  in 32 hours

 

So....  in one hour...5 machines can make     12000 / 32  = 375 widgets

 

So....each machine can make      375 / 5  = 75 widgets per hour

 

So...to make   150 widgets in one hour...we need  150 / 75   = 2 machines
