The officejet h470 printer takes twice the time required by the hp officejet
pro k5400 color printer to photocopy brochures for the New Bretton Arts annual
arts fair. If working together, the two machines can complete the job in 45min,
how long would it take each machine, working alone, to copy the brochures?
:
Let t = time required by the HP
then
2t = time required by the OJ
:
Let the completed job = 1
:
A typical shared work equation:
+ = 1
Multiply eq by 2t, results:
2(45) + 45 = 2t
90 + 45 = 2t
t =
t = 67.5 min, the HP working alone
:
I'll let you figure out the time for the OJ
