Question 1198432
<br>
Fyona can do the task in half the time that Emmanuelle takes.<br>
That means Fyona works twice as fast as Emmanuelle.<br>
So when taking 3 hours to do the task together, Fyona does 2/3 of the task and Emmanuelle does 1/3.<br>
Each working alone....<br>
Emmanuelle: 1/3 of the task in 3 hours, so 9 hours to do the whole task alone.
Fyona: half the time Emmanuelle takes, so 9/2 = 4.5 hours.<br>
ANSWERS: Emmanuelle 9 hours; Fyona 4.5 hours<br>
