Rhea is writing a paper, and she notices that she can write 1.25 pages every 2 hours.

She estimates that she can finish the six-page paper in 6 hours.

Is her estimate reasonable? Why or why not?

Rhea's estimation is unreasonable.

Step-by-step explanation:

Identify what you know:

1) Rhea calculates that she can write 1.25 pages every 2 hours

2) Rhea is calculating how long it would take her to write 6 pages.

Using Rhea's initial calculation, we can figure out roughly, how long it would take her to finish 6 pages.

First we need to divide 6 by 1.25, to figure out how many "2 hour" periods it would take Rhea.

6/1.25 = 4.8

4.8 x 2 = 9.6

It would take Rhea roughly 9.6 hours to finish 6 pages, which is 3.6 hours more than her original estimation. Thus, her estimate is unreasonable.
