Question

mary travelled 70 miles/hour due north. this is an example of a acceleration b distance c speed d velocity

Explanation:

Velocity is speed with direction. Here, 70 miles/hour is the magnitude (speed) and due north is the direction. Acceleration is the rate of change of velocity. Distance is a scalar quantity without direction. Speed is a scalar quantity only representing the magnitude of motion. Since the value has both magnitude and direction, it is velocity.

Answer:

D. velocity
