Question 286613: ramona can do a job in 12 days after she has worked for 4 days she is joined by carlotta and it takes them 2 days working together to finish the job. How long would it have taken carlotta to do the whole job herself? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! 4/12=1/3
Ramona completed 1/3 of the job before Carlotta joined her
they finished 2/3 of the job in 2 days together
2/12+2/c=4/6
1/6+2/c=4/6
2/c=3/6
2/c=2/4
c=4
Carlotta could have done the job alone in 4 days.
