There are several flyers that need to be printed. Working alone, Printers A, B, and C can finish the task in 3, 4, and 8 hours, respectively. If we use all three printers simultaneously, how many minutes will it take to finish the printing task?

A will do 1/3 of the task in 1 hour. 

B will do 1/4 of the task in 1 hour. 

C will do 1/8 of the task in 1 hour. 

Together, they do 1/3 + 1/4 + 1/8 of the task in 1 hour. 

How many hours does it take?

   combining their rates for the one job:

 

1 job / ( 1/3 + 1/4 + 1/8)  = _______    hours     ( multiply this answer by 60 to get 'minutes')
