Question 355324: Craig and Cara, working together, can rake the yard in 8 hours. Working alone, Cara takes 4 times as long as Craig. How long does it take Craig to rake the yard alone? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! Let Craig take x hrs and Clara 4x
1/x + 1/4x = 1/8 Time it takes them working together to do 1/8 the job.
8+2=x
x=10 hrs. Time it takes Craig to rake the yard.
