It takes Rebecca and Hunter  2 1/4 days to complete a project. Hunter works one-thirds as fast as Rebecca. If Hunter wants to do the project alone, how long would it take Rebecca?

Rebecca and hunter complete the work in 9/4 days .

Their one day work is 4/9

Hunter works one third as fast as Rebecca

If rebecca works/ complete in x days , Hunter complete the work in 3x days

so their one day work is 1/x +1/3x=4/3x

4/3x =4/9

x =3

so Rebecca will alone complete the work in 3 days and Hunter can alone complete the work in 9 days
