Let's say that number is hmmm "a"
now.. twice "a" is 2*a or 2a
4 less than that is " 2a - 4"
now, the product of those two fellows is 286, well ok
a( 2a - 4) = 286
thus
or in other words divide 7.5 by 9 to get your answer which is .83333.. which is the same as 5/6 of a page per minute.
Check
5/6 + 5/6 + 5/6 + 5/6 + 5/6 +5/6 +5/6 +5/6 +5/6 + 45/6 or 7 3/6 = 7 1/2
.21 as a fraction would be 21/100
