The graph represents the distance in miles, y, that Car A travels in x minutes. The function y = 56

Question

x represents the distance, y, that Car B travels in x minutes. Both cars are moving at a constant rate of speed. Which BEST compares the rates of the two cars?

Responses

A. The rate of Car B is 16
of a mile per minute greater than the rate of Car A.The rate of Car B is 1 6 of a mile per minute greater than the rate of Car A.

B. The rate of Car A is 12
of a mile per minute less than the rate of Car B.The rate of Car A is 1 2 of a mile per minute less than the rate of Car B.

C. The rate of Car B is 16
of a mile per minute less than the rate of Car A.The rate of Car B is 1 6 of a mile per minute less than the rate of Car A.

D. Car A and Car B are traveling at the same rate per minute.

Answer 1

D. Car A and Car B are traveling at the same rate per minute. This is because both cars have a constant rate of speed and their distances are represented by the same formula with the same coefficient (56).
