9) Alyssa takes 10 hours to repair the roof. It takes Mike 11 hours to complete this job. How long would it take if they worked together?

I'm sorry for "awnsering" this I needed some points

11 hours

Step-by-step explanation:

so here the thing alyssa takes 10 hours

but with one more person to help it take have the time to do so that would be 5.

Mike take 11hour to do a job so we do the same thing but with mike so it will be half the time 6

and if you add them together you get 11 soo it would take 11 hours to do all of the work together

(sorry if wrong) but hope it helps
