Solve the problem.Suppose that two cars, both traveling at a constant speed of 60 miles per hour, approach each other on a straight highway. Initially they are 12 miles apart. Let x represent minutes. Give an absolute value equation whose solution gives the times when the cars are more than 8 miles apart. Solve the equation. Interpret the meaning of the result.
A. 
> 8; x < 2 or x > 10; Before 2 minutes or after 10 minutes the cars are more than 8 miles apart.
B. 
< -12; No solution; The cars will never be more than 8 miles apart.
C. 
> 4; -2 < x < 2; After 2 minutes or 2 minutes earlier the cars are more than 8 miles apart.
D. 
> 8; x < 4 or x > 20; Before 4 minutes or after 20 minutes the cars are more than 8 miles apart.
