A motorcycle is being driven on a road moving north at 40 miles per hour. A car is driving on the same road moving south at 40 miles per hour. Which of the following is true?

• The motorcycle and car are moving at the same velocity and the same speed.

• The motorcycle and car are moving at the same velocity but different speeds.

• The motorcycle and the car are moving in opposite directions, so their speeds are different.

• 
  The motorcycle and the car are moving in opposite directions, so their velocities are different.

A car is traveling 40 kilometers an hour. It turns right at 40 kilometers per hour. The action the car takes changes its

• speed

• acceleration

• only direction

• only speed
