If a car is moving backward along a road, can its speed be measured?

• Yes, it can, because the car does not have friction acting on it.

• Yes, it can, because the car travels a distance in a certain amount of time.

• No, it cannot, because speed can only be measured if the car is moving forward.

• No, it cannot, because the distance traveled backward by a car cannot be measured.

Scientists discover an asteroid that is moving through space. What information is needed to determine the average speed of the asteroid?

• the mass and size of the asteroid

• the distance the asteroid is from Earth

• the direction the asteroid is moving and its distance from Earth

• how far the asteroid has moved in 24 hours
