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 16 miles apart. Let x represent minutes. Give an absolute value equation whose solution gives the times when the cars were 10 miles apart. Solve the equation. Interpret the meaning of the result.
A. 
= 10; x = 3 or x = 13; After 3 minutes or after 13 minutes the cars were 10 miles apart.
B. 
= -16; No solution; The cars will never be 10 miles apart.
C. 
= 10; x = 6 or x = 26; After 6 minutes or after 26 minutes the cars were 10 miles apart.
D. 
= 6; x = 3 or x = -3; After 3 minutes or 3 minutes earlier the cars were 10 miles apart.
