We were told that she types about ⅓ of a page every ⅙ of an hour. Let x represent the number of pages that she types per hour. We wold have the following equations:
1/6 hour = 1/3 page
1 hour = x page
By crossmultiplying, we have
x * 1/6 = 1 * 1/3
x/6 = 1/3
By crossmultiplying again, we have
3 * x = 6 * 1
3x = 6
x = 6/3
x = 2
Thus, she types 2 pages per hour
