So,we know that it take 0.8 of a minute or 48 seconds to read each page of a health book, so it will take 300 seconds to read 6.25 pages. As a result, it will take 10.5 minutes to finish reading 6.25 pages and also taking a test. Hope it help!
Since, each test on a page takes 5.5 minutes while each page take 0.8 minutes to read. So, for 6.25 pages. So, to give the test of 6.25 pages, time will be:
When you see an equation in this format, it's called slope-intercept form (y=mx+b, with m being slope and b being y-intercept). So in this case, by looking at our formula, we can tell right away that our slope, or m, is 2/3 and our y-intercept, or b, is 12. HTH :)
