Question

Nakita recorded a video of homecoming highlights of the senior class and now everybody wants a copy. She promised to have 25 ready the next day but suddenly realized that it will take her ten hours to do that. Her friend, Abby, volunteered to help and she can do the job alone in 15 hours. How long will it take the girls, working together, to complete the job?

Answer 1

I would take  because it would take nakita 1 hour to do 2 and a half herself and it would take abby 1 2/3 to do it herself
