Answer:
h = yX -yr
Step-by-step explanation:
X=r-h/y
X - r = h/y
y*(X-r) = h
h = yX -yr
Find unit rate of pages read per minute:
(5/8)/(2/3)
(5/8)*(3/2)
(5*3)/(8*2)
(15)/(16)
15/16
Kenny reads 15/16 pages every minute (unit rate)
Since the Power is directly proportional to the velocity, their ratio

is constant.

which is a proportion:
500 : 1000 = x : 1728
that can be easily solved:
x = (500×1728)/1000 = 864kW
