Question

The captain told the passengers that the plane is flying at 450 miles per hour this information describes the plane

Velocity
Speed
Acceleration
Direction

Answer 1

speed, why velocity has direction acceleration Is a change in speed and it doesn't give a direction so it's speed

Answer 2

The correct answer is speed.

Step-by-step explanation:

Time rate of change in distance is called as speed. On the other hand, time rate of change in displacement is called velocity. The captain told time rate of change in distance (450 miles/hour) because he did not mention the direction. Hence, 450 miles/hour describes the speed of the plane. We do not identify any relation of this information with direction and acceleration.
