Answer:
112 miles
Step-by-step explanation:
93.60 - 60 = 33.60
33.60/0.30 = 112
If x is the age of S
And y is the age of K
So we have x=y+3
And the second equation is x-3 + 2/3)y = 12
We have to solve the system
x-y=3
x+2/3y=15
we find x=10.2 and y=7.2

800+16x=720+21x
80+16x=21x
80=5x
X=16
So 16 hours :)
342-72=270
270-72=198
198/2=99
Therefore the width is 99
