Beware the math geek... suppose you read for 18 hours...
530.00 = total pages
18.00 = hours
29.44 = pages / hour
60.00 = min / hour
2.04 = min / page
Pssh, that's easy.
Of course, you'd have to be pretty filled with the spirit to read for 18 hours straight without a break.
Seriously, there are some pretty cool things to be gained from a fast reading of the book of mormon. And of course there's tons of things to be gained from a slower reading.
