14. 15. Vince (V) was 12 minutes early to class, Denise (D) was right on time, and Kevin (K) was 3 minutes late. Which timeline represents the students' arrival to class? A KD + -15 -12 -9 -6 -3 0 3 6 12 15 + 9 B. DK V + + + + -15 -12 -9 -6 -3 0 3 0 3 6 9 12 15 C. V DK + + + + + + -15 -12 -9 -6 -3 -6 -3 0 3 6 9 12 15 D. K D K V + + + -15 -12 -9 -6 -3 0 3 6 9 12 15

Answer:

The answer is C.

Step-by-step explanation:

Right on time means 0, not negative nor positive because the person is right on time. Denise (D) would be put on 0.

12 minutes early would mean 12 minutes before 0, thus 0 - 12 or -12. Vince (V) would be on -12.

3 minutes late would mean 3 minutes after 0, thus 0 + 3 or 3. Kevin (K) would then be on 3.

Follow the conditions:

V = -12

D = 0

K = 3

The letter that follows these conditions is C. Hence, C is the correct answer.
