Question

Two cars are traveling along the same highway. The distance, d, in miles, from San Francisco after h hours spent driving is described for each car below.

Car A:
d = 60h + 20

Car B: h d
0 60
2 160
4 260

Select three statements that are true.

A.Car A is traveling at the same rate, in miles per hour, as Car B.

B.Car A is traveling at a faster rate, in miles per hour, than Car B.

C. Car A is traveling at a slower rate, in miles per hour, than Car B.

D.Car A is originally closer to San Francisco than Car B.

E .Car A is originally at the same distance from San Francisco as Car B.

F.Car A and Car B are at the same distance away from San Francisco after 4 hours.

Answer 1

Car A is traveling faster at the checkpoint because it must go past the speed of car B to reach the same distance.

Step-by-step explanation:

Car A is traveling faster at the checkpoint because it must go past the speed of car B to reach the same distance.

To determine which car is traveling faster at the checkpoint, we need to compare their velocities. Car A has a positive, constant acceleration, which means its velocity is increasing. Car B, on the other hand, travels at a constant speed, which means its velocity remains the same.

Therefore, Car A is traveling faster at the checkpoint than Car B.
