Question

Julie calculate that she types about ⅓ of a page every ⅙ of an hour. What is Julie's unit rate in pages per hour?A. 18 page per hourB. 2 page per hourC. ½ page per hourD. 1/18 page per hour

Answer 1

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
