Question 1167717: If a woman works for 3 1/2 hours per day, she can finish a piece of work in 10 days. How many hours per day should she work to finish the same piece of work in 7 days? Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! 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.
