It took Margie 2 1/4hours to write a 1 1/2 page research paper . What was her hourly writing rate
WARRIOR [948]


Margie would take 1 hour and 30 minutes to write 1 page of her research paper. Think of it like a proportion:

2.25/ 1.5 = x/1

2.25 is the 2 1/4 converted which is the amount of hours she took.

1.5 is the 1 1/2 converted which are the amount of pages she wrote total.

1 on the right side of the proportion represents  1 page.

And x are the amount of hours used  to write 1 page.

And in solving that proportion  it would result in 1.5 or 1hr. and 30 min.
