Question

Working with your cousin you can refinish a table in 3 hours. Working alone, your cousin can complete the job in 7 hours. How long would it take you to refinish the tab look alone?

Answer 1

the answer would be 4. if the cousin could do it at 7 hours and now when they work with the cousin it finishes in three that means that the person takes away 4 hours so if they were to work alone that would be 4 hours, hope its right!
