Mr Loh used two printers with different printing rates for a printing job. He started Printer T at 21 00 and started Printer U two minutes later. He stopped both printers at 21 05. The graphs show the total number of pages printed by each printer from the start of printing.

- What was the difference in the number of pages printed by the two printers from 21 00 to 21 05?
- Which printer, T or U, has a faster printing rate? What is the difference in the number of pages printed by the printers in one minute? Give your answer in this format. (Eg A, 1)
