Answer:11 honestly have no idea but im going to give my best answer it is 31
Answer:
15
Step-by-step explanation:
determine the numerical length of AC
We know that Ac is equaled to ab and bc because they are the segements between ac
3x 4x+8
A-----------------------------B----------------------------------C
|<----------------------------5x+10 --------------------------->|
AB + BC = AC
solving for x
3x + 4X + 8 = 5X + 10
3x+4x-5x= 10-8
2x=2
x=1
Now sub that in for ac
AC= 5x +10
AC= 5(1) +10
AC= 5 +10
AC = 15
So if it is 60 miles per hour it is basically 60 miles per 60 minutes. 
when you simplify it, it is going to be 1/1=1 The answer is 1 mile per minute
