There were reports that researchers from SRI International are developing a super-miniature, high-tech robots that can be used in micro assembly plants. Robots in factories are efficient and can carry a lot of work in minimum time.

I went to a factory earlier this year where they are using robots in assembly plants. The factory head told me that 6 robots can finish packing 20 boxes in 2 hours. They plan to buy two more robots. With the additional 2 robots, how many hours will it take to pack 20 boxes? How many boxes can the 8 robots pack in 10 hours?
