Sean read 15 of a book in = 112 hours,
so, 1 of a book in = 112/15
Now, 12 of a book would be: 112/15 * 12 = 112/5 * 4 = 89.6
89.6 = 89 6/10 = 89 3/5
In short, Your Answer would be 89 3/5 hours
Hope this helps!

Answer:
The answer is B-15:18 based on a 24hr clock
Areashaded=areabigcircle-areasmallcircle
areacircle=pir^2
d/2=r
big diameter=20.4, so radius i 20.4/2=10.2cm
small is 10.8/2=5.4
so
big-small
pi10.2^2-pi5.4^2
pi(104.04-29.16)
pi(74.88)
using 3.14=pi
235.1232 cm^2
answer is B
