Yesterday, I was ready to bake a delicious batch of cakes with the help of my 5 trusty machines. We planned to work for 10 hours to ensure every cake was perfect. But today, things changed! I received an even bigger order, and now I can only use 2 of my machines.

The question is, how long will it take my 2 machines to finish the job that originally would have taken 5 machines 10 hours?
