H=270/45
To find how many hours it takes to read the rest of the book, you have to divided the remainder of pages (270) by how many pages are read in a hour (45)
308? It seems to be at .7 if an inch so I divided 440 by 10 which was 44, then I multiplied 44 and 7 and I got 308
(8 min) x ( day/1,440 min) x (20 /day) x (365 da/yr) x (35 yr) =
(8 x 20 x 365 x 35) / (1,440) days =
(2,044,000) / (1,440) days =
1,419-4/9 days = 3.89 years
Rounded to the nearest year: <em>4 years</em>
At a pack a day for 35years, I would have expected more than
4 years' damage. But I've checked my math and haven't found
the mistake, so I'll let that be my answer.
