If a car is moving backward along a road, can its speed be measured?
A. Yes, it can, because the car does not have friction acting on it.
B. Yes, it can, because the car travels a distance in a certain amount of time.
C. No, it cannot, because speed can only be measured if the car is moving forward.
D. No, it cannot because the distance traveled backward by a car cannot be measured.
B. Yes, it can, because the car travels a distance in a certain amount of time.
