Kelly can read five pages of her fiction book or two pages of her history textbook in seven minutes. If Kelly wants to read thirty pages of each book, for how many minutes in total must Kelly read?
5 pages = 7 minutes
5 x 6 pages = 7 x 6 minutes
30 pages = 42 minutes :D
As Max found, it takes 42 minutes to read 30 pages of fiction.
2 pages of History = 7 minutes
2 x 15 = 7 x 15
30 pages of History = 105 minutes. So, her total reading time:
42 + 105 = 147 minutes.
