A batch of [[$ 1200 $]] copies of flyers will be produced on a computer that can be connected to either printer A or printer B. Using printer A for [[$ 1 $]] h [[$ 55 $]] min and then using printer B for [[$ 1 $]] h [[$ 30 $]] min will complete the job. The same job can be done using printer B for [[$ 1 $]] h [[$ 20 $]] min and then printer A for [[$ 2 $]] h [[$ 10 $]] min. How many flyers do printers A and B print per minute? How long does the job take if you only use the faster printer? (Source: Finnish matriculation exam, spring 1998)
