<PRE><B>Question 1167717</B>
if she works 3.5 hour a day and it takes her 10 days to finish a piece of work, then it takes her 3.5 * 10 days = 35 hours to finish the piece of work.


the amount of work required is 35 hours to finish the job.


this remains the same.


let x = the number of hours it takes her to finish the finish the job in 7 days.


you get x * 7 = 35


solve for x to get:


x = 5


it would take her 5 hours per day to finish the job in 7 days.


5 * 7 = 35
3.5 * 10 = 35
